I've been comparing netbooks in an effort to find an ultra-portable to replace my stolen 17" MBP. That thing was too heavy! I decided I would get something cheap and light, because the new computers are about as fast as my old one, and I want more portability. The screens on the little iPhones and iPod touches aren't big enough for me, and I'd rather have a 12 inch netbook instead of a 10 inch one. The problem is most 12 inch netbooks weigh 3.2 lbs, and they cost about $450 or more if they have 2 GB of RAM (a minimum for me). I can't see spending that much, except that the MBA is more than twice that, has a smaller hard drive, and only has a 1" bigger screen. I like the fact that Apple gives a more portable alternative, but the little 2 lbs. 11 inch MBA, which might fit the bill for me, has not SD card slot, and frankly it has a hard drive that is just too small. If it had that 264 GB HD available in the 13" MBA, and a back-lit keyboard, like my $49 prepaid Motorola flip cell phone has, it would be such a winner that I might actually go for it. Still, it's very expensive, but probably worth the money. With the netbook I was thinking about getting, I was planning to spend $100 to replace the 160 GB HD with a 500 GB HD anyway. The thing is I was going to have to pay even more for an upgrade to Windows 7 Ultimate Home Edition or whatever it's called. I HATE Windows 7 though, and I can just see myself regretting the $400 savings I would experience by not buying an 11" MacBook Air. I think the Mac OS might just be worth the extra $400, especially since the netbook is 3.2 lbs vs. the MacBook Air at 2 lbs. The main problem I have is the fact that if I go Apple, I will have to get the heavier model, because I want a larger hard drive (hopefully I can replace the current one with a 500 GB drive). I just don't want to do without a built-in SD card slot. I connect too many devices (printer AND external HD). One thing that's nice is the fact that the 13" MBA now has that SD card slot while having the extra USB port vs. the earlier model. The fact that I can upgrade the RAM to 4 GB (my 17" MBP was maxed out at 3 GB) is awesome! It looks like I might just have to save up some and get a 13" MBA. I wish the little one had an SD card reader, the ability to go to 4 GB and had a bigger hard drive. That would be one amazing little dude!
