Well, I went to see the MBA at the apple store. WOW.
I had looked at them on the apple site, and was comparing really from there. Looking at it, it truly indicated that there is NO comparison.
As mentioned early on, form factor is critical. I'd consider a windows workaround if there was a better/cheaper option, but at this point it is clear that there is not. No netbook will sit as cleanly and with as little impact on depth/weight in my briefcase. Since I carry my work dell around too, this was critical as I travel and take this stuff around a LOT.
No netbook Ive found sits as slimly in a flat pile as the MBA. Nothing. Including the X300, which is the windows apparent winner when it comes to a PC ultraportable. The Asus eee 1008HA seashell is thicker, at 27mm.
So I cannot find anything that will work as well. Add to it that the MBA is 13", versus netbooks which have smaller keyboards, 10-12" screens, and the MBA is really a winner.
As far as reliability, my last-gen 15" MBP has been a champ. Reading consumer reports today, the reliability report shows apples right in the middle of the pack, and dell lower. The best laptops Ive had are IBM thinkpads and MBPs. So I find that a good assessment. MBA was rated the best ultraportable, and as far as I can see, this is absolutely the case.
As far as the 2GB argument performance-wise, Im currently running 4GB 667 MHz DDR2 on my 2.6 GHz C2D. I routinely run parallels allocating 1GB to the Windows XP, and run everything else just fine, so I guess on 3GB.
Running a number of programs, and Im taking up about 697MB. I am still running my early-gen I mac mini without issue, and it only has 512 MB of ram for mail, itunes and internet. Very reliable.
For the specific software which I'll be running, it is not going to become bloatware going forward. I am positive of that. As I understand it snow leopard takes a smaller footprint and is more efficient than leopard. I don't see where I can go wrong. I win on form factor, and am pretty positive that over the next, say, three years, for the specific sw I need to run, I'll be fine. I win on size, weight and application capability.
So, hatred towards macs aside, and given that I have not seen a netbook which has a better form factor or profile than the MBA, any other thoughts? I cannot find a fault against it.
