I've been researching the different models of the MBA, trying to decide which one would be best to get my husband for Christmas. He has used my hand-me-down MBP for a couple of years now, which is the 15 inch 2007 model. Pretty much all he does is use the web and email. Occasionally he uses Photoshop to resize an image from a digital camera for posting an item for sale on craigslist, eBay, etc. When he's online, he is usually streaming a Netflix movie or playing spades at pogo.com. He is already accustomed to not having a DVD drive because at some point during the past two years, the drive in his MBP completely stopped working (we have no idea why). That's the only thing wrong with it, other than normal wear and tear, so I figure we can try selling it on eBay after the holidays. Anyway, he only uses the laptop while sitting on the couch and doesn't take it anywhere. I still think the MBA would be a good choice for him because I assume it's cooler and I know it's lighter...the fan in his MBP comes on fairly often and loudly during his typical web use. I don't think he'll notice much of a difference dropping from a 15 to 13 inch screen. My question is...is there much of a reason to buy the latest model MBA or is it safe to go with a used 2010 model that's in "like new" condition? Obviously the cost difference is substantial ($300+), so if the 2010 one would suffice for him, I will go that route. Or, is it better to spend the same money on a MBP that (maybe) has better specs? I think he would like having the newest trackpad which appears to have been introduced in the 2010 MBA. Oh...and he's currently accustomed to OS 10.4.11 because, with a non-functioning DVD drive, we never upgraded his laptop. I would appreciate any advice...thanks!
