Incorrect assumption - as a result,
...your math is wrong.
60 psi is 60 psi, period. If the tire pressure in the truck is 60 psi, then the pressure on the road is 60 psi. You can't double the tire pressure and triple the pressure on the road as a result - you'd have a truck that either bounced, or sank. Newton's laws (net vertical force = 0 for no acceleration in the vertical direction) have to be met.
It doesn't matter if my math is wrong or my assumption about surface area is wrong. The simple fact remains that the tractor trailer has 14.666 times the weight of the car but only 4.5 times the number of tires of the car. Even if that means that factor of 3.25 is completely compensated by the tire in a ratio of 60/35, you're still applying roughly double the pressure over an area 3.25 times greater, 4.5 times as often.
(regarding PSI, while I think your assumption probably roughly holds, we also have to take into account the fact that as these tires have a different composition, they are also going to dissipate weight differently. Tractor trailer tires are not only larger, but they are also thicker. That means that there is more rubber in each tire to distribute force from the truck to the road. i.e. its tendency to deform as a result of weight applied is what affects its PSI. Consider an extreme example: A fictional monster truck tire almost completely rubber with a very small chamber inside the tire. If it is sufficiently small, you could even create a vacuum inside this chamber, and the structure of the tire could still handle the stress. So, regardless of the amount of fictional weight you placed on the tire, that chamber would still have a PSI of 0 because there's no actual gas to be pressurized. Thus, if the tractor trailer tire has more structural rigidity, a higher portion of its weight is directly applied to the road via the resistance of the tire to deformation from pressure.)

I don't think this will serve Apple any good to stop podcasters from using Pod in the name. It will only create ill-will and lessen the use of Pod which I would think would be a good thing for Apple.

I don't think Pages is horrible. It's not great, but it isn't quite as bad for me as everyone else finds it. I don't use it all that much (Keynote gets used far more than Pages does).
I'm with you. I'm new to the world of Mac and I want to stay clear of Word. It's not a great app, but it's something I'm getting used to.
Same with Keynote, different approach, but I like it better than the world of PP.

If you are correct the i5 processors are obviously going to be more expensive meaning they will have te same situation with the backlit keyboard
The i5 processors are the same price (or less) as the LV C2D they're using now. The SL9400 costs $284. The i5-2537 that's in the Samsung Series 9 costs $250.
The SL9600 costs $316. The comparable i7 LV SB processor costs $316.
Plus there's no 320m cost, so that component costs conceivably go down with a SB MBA making room to re-add the BL keyboard.
Speaking of:
It is the same with the backlit keyboard on the MBA, which was for years a standard feature. To take it away now in order to 'differentiate' it from the pro models, is total bull....!!
Although of course no-one but Apple knows the real reason - I maintain that the BL keyboard wasn't removed due to "luxury" or size, or battery life. I'm 99.99% sure it was to keep the cost down, to hit that $999 price-point and keep 30% margins.
Therefore, if a SB (or IB if Apple decides to leave it's new marquee portable completely stagnant for almost 2 years...) MBA saves on component costs via not being able to use the 320m - it could conceivably put the BL keyboard back in.
Besides:
Wanting a backlit keyboard isn't as unreasonable as you think it is... esp since the previous gen Air had it.
This. :)
Why does everybody repeat the mantra 'Ivy Bridge'? Will it make the Intel's HD 3000 perform better in some kind of mysterious magical way? Or do you expect that by the time IB is released Intel will have developed a new, presumably better, IGP? Shall we expect the same comments "Intel IGP sucks I'm gonna skip IB and wait for whatever-bridge" again next year?
Exactly. If I had loads of time on my hands, I know I could find loads of comments (probably from the same posters) last year saying "Ugh, Arrandale IGP sucks, I hope Apple waits till Sandy Bridge!"
There'll be just as many Intel IGP haters when Ivy Bridge is released, and only "matches" the 320m.
Get with it people - at some point we're gonna lose the 320m. If it's not with SB, then it'll be with IB and the graphics will still not get "better" than the 320m. It sucks - I agree - but it's inevitable.
Almost all people in this thread sound like they want to buy a Mac mini (MBA), but want at the same time the features of a Mac Pro (MBP). Silly.
Yeah, this is the MBA-forum, but it does not make this discussion thread better.
:rolleyes:
What are you talking about? We're all here 'cause we love the MBA. Would we all like a more powerful MBA? Of course - why not? Right now the MBP's rival the some late-model Mac Pro's. Why not desire more power in a portable (CPU, Graphics, or otherwise?).

I've got a question and I didn't really want to start a new topic for it. I got folding going an here (using terminal) and it's been going for a few days. I downloaded the folding tracker widget and clicked the icon on the back and it still wont recognize by user name on the site (it doesn't find any users) and I looked in terminal and I found my ID number and put that into the widget and it doesn't get any info from it. How long does it take for the site to recognize new accounts? And why the heck after like three days can I not get any info on it? I'm getting annoyed I wanna see my stats.

Somehow I was expecting to see a lot more praise and excitement for the 3DS after it launched....
The 3D effect seems to trigger mixed reactions. Other than that...there really doesn't seem to be anything truly exciting about it? I don't see any "wow, those graphics!!" or "holy cow, this thing is fast/powerful" type comments.
The general vibe I am getting from here and other places is more like "pretty neat", rather than "wow, so awesome". :confused:
Because that's exactly the response.
The 3DS graphics are roughly the same as PSP, so nothing new (and in fact, so 2005) and hence nothing to jump up and down about. Sure, it's better than the DS...
The 3D is mixed reactions because it's...meh. The consensus is that it's cool for a while, after which your eyes hurt, or the battery dies, or you get fed up with losing the sweet spot all the time. It's got the wow factor of being a new technology, but no real lasting appeal.
I had a 3DS for three days, sent it back. Totally underwhelmed.

P4s can't go Dual. It's sorta like the G3, it's just not designed to do that. It wouldn't work.

Mac vs. PC: The stereotypes may be true
By Brandon Griggs, CNN
April 22, 2011 -- Updated 1915 GMT (0315 HKT) | Filed under: Web
(CNN) -- Remember those Apple ads that cast the Mac as a 20-something, self-satisfied hipster while the PC was portrayed by an older, square-looking guy in a brown suit?
Well, those characterizations, unfair as they may be, appear to have some truth to them.
An unscientific survey by Hunch, a site that makes recommendations based on detailed user preferences, found that Mac users tend to be younger, more liberal, more fashion-conscious and more likely to live in cities than people who prefer PCs.
Of the 388,000 Hunch users who responded to a question about computer loyalty, 52% identified themselves as PC people as opposed to 25% who said they are Mac devotees. Hunch then cross-referenced those responses with answers to other questions to draw cultural distinctions between the rival Mac and PC camps.
The results suggest Mac users can be seen, depending on your perspective, as bolder and more creative -- or elitist and more pretentious.
The report found that 67% of Mac users have a college or advanced degree, as opposed to 54% of PC users. Mac loyalists are 80% more likely than PC users to be vegetarians, and, unlike PC fans, would rather ride a Vespa scooter than a Harley.
PC users' tastes trend towards casual clothes, tunafish sandwiches, white wine, Hollywood movies, USA Today and Pepsi. Mac users prefer designer or vintage duds, hummus, red wine, indie films, The New York Times and (we're not making this up) San Pellegrino Limonata.
Mac users also are more likely to describe themselves as computer-savvy and "early adopters." PC users tend to describe themselves as better at math and less likely to throw frequent parties.
"I fit the typical Mac user on every count. Guess I'm not as unique as I thought. Depressing," wrote one commenter on Hunch's blog.
Since Hunch's first survey of Mac vs. PC users in November Apple has ridden the success of such high-profile products as the iPad and iPhone 4 to become the world's most highly valued tech company. Despite that hot streak, Hunch found that slightly more people in its new report -- 52%, up from 50% a year and a half ago -- now identify themselves as PC users.

San Pellegrino Limonata rocks.
Tunafish sandwiches? LOL!! Losers. ;)

I am definitelynot a 'power user', but I am a hardcore gamer. And when I see a friend with a year old PC playin Warcraft with less jumpiness then my 6 month old powermac, it makes me want to switch. Power does matter to me, and you cant get much power for the amount of money I have when it comes to computers from apple.
So what do you use your mac for except for playing games???
