I bought the 1.8 with the SSD. Yup, $3,200 spent on the MacBook Air. And I feel great so far about the purchase and I can't wait to take 3.5 pounds out of my bag when I travel to Asia.
Does it have everything I want?
Basically, yes, with one exception. (I'll even share some of my fears too.)
Why I Bought the MacBook Air
1. It's light and thin. I don't care about the other dimensions since I am not buying a less wide bag. Thin means I can put more books, files, etc. in my bag. This is why THIN matters to global executives.
3. I don't bring DVD or CD's with me on the road.
4. Full sized keyboard and screen. Awesome.
5. CPU speed is more than fine. Remember where we were 3 years ago. I just hope the SSD gets rid of the bottleneck with the hard drive so this is a fast computer overall.
6. I always travel with an Airport Express. (I like to be able to work anywhere in a hotel room.) And for the 1 or two times a year I need an ethernet cable, I bought the dongle. Honestly, this really is not that big of a deal.)
The ONE MAJOR bummer for me:
1. No swappable battery. Yes, I fly business class with power plugs, but there are times when I am giving presentations all day long and I need a second battery. This is a major bummer.
My Fears:
1. Is the GPU powerful enough? I give photo rich presentations with builds and I can't have a computer which lags. I hope this is not the case.
2. Apple quality. We all know Apple's quality has been on a rapid decent in the past few years. Horrifically buggy software, heat issues, fit and finish, displays, etc., etc., etc. After spending so much for a laptop with some known specification tradeoffs, I really will be upset if there are quality issues.
3. Battery life needs to be 5 hours. Apple really needs to stop lying--and it has been lying--about battery life. (When I turn off all wireless, dim the screen all the way, and leave my laptop idle until the battery dies and still only get 70% of Apple's claim, it is lying.) Steve was very clear when he discussed 5 hours of battery life: wireless is on and using office-class applications. I expect this to be the case, and if I have wireless off on the plane, I expect to get a lot more than 5 hours. Again, these lies really hurt the integrity of Apple's brand.
So, I am pleased enough with the MBA specs and trade-offs to buy the top-of-the-line model. If the lack of swappable battery means I have to bring my MBP or if I can't run the presentations seemlessly with no lags between builds, I will sell the MBA and take the loss.
But I for one am hopeful the MBA meets my needs.
