My recommendation to any prospective purchaser of an MBA would be not be put off by its C2D processor. Only the most processor intensive application will run significantly faster on an i series processor than it will on a C2D.
Sigh....
Ok, you want to drag it out? Sure why not, I've got some free time.
He has a mid-2009 13" MBP. A light machine that is easily portable. And his tasks are as follows:
"I need it for taking notes, doing some presentations, writing research paper, and all that good stuff that high schoolers do"
All of that can be done perfectly fine with his existing laptop without buying into an already outdated architecture. Not only an outdated architecture but a slow one. Yes, they're binned SU/L9400's, but that's 3 year old architecture that is slower than his current laptop and running under extreme throttling from OSX.
The underlined portion for youth today (and for nearly the last decade), simply to cut the bulls**t here, is downloading episodes of family guy and converting them into mp4 for itunes/ipod/iphone. That and ripping CD's/DVD's or converting audio. And there you most certainly will see dramatic increases on a SNB chipset. The current 13" MBP blows the mid-2009 model out of the water in Futuremark and video trans/encoding.
Moreover, people who run such apps know who they are. The 13 inch MBP's graphics are significantly inferior to those of the MBA
Quote where he says anything about gaming in the original post. Gaming shouldn't be taken seriously on a 13" MBP, and especially not an 11" MBA. Graphics? That's cute. They have the same amount of memory available to their GPUs so Photoshop GPU acceleration would be roughly the same. Only the overall application performance would be worse thanks to a slower and more heavily throttled CPU.
and the iPad is a large iPhone, which in no way can really substitue for a genuine computer.
Says the guy with two laptops (MBP, PB), one ultraportable (MBA) and a smartphone (IPhone4). Gee, I wonder why you found no real use for the Ipad. There are plenty of people who do find it useful and working on a college campus I can say I see many students, including a few in classes I teach, taking Ipads to class instead of laptops.
There a number of valid reasons to select a 13 inch MBP or an iPad over an MBA but the MBA's C2D processor is not one of them.
Yes, it most certainly is. Stop being obtuse.
EXECUTIVE SUMMARY: It is a big mistake to be a spec whore.
Executive summary? From someone who seems to lack an understanding of the actual hardware involved in the discussed products? That's adorable.
To the OP: Listen kid. Save your money. Spend it on something useful, like beer or a girlfriend. Those extra 2 pounds of laptop are not going to kill you (considering the weight of most kids backpacks). If you really, really, absolutely, positively must have something smaller and all you really need is notes and presentations, save up an extra $100, grab an ipad with the hdmi out and a bluetooth keyboard. You'll still be way under the price of a new MBA, it's lighter and smaller, and you'll still have the 13" MBA at home if you get the entry wi-fi Ipad.
If it were a lateral move from your current laptop to a new 11" MBA, that's one thing. But a high school kid spending $500 just to do it coming from a mid-2009 13" MBP? Pointless.
