"13 MBA is a great laptop, don't be fooled by the specs"5.0 starson by hjklgh
Pros: Size, weight, thickness, sturdiness the general build quality and form factor is outstanding, best on the market by far. Performance is excellent even with old processor technology. Battery life. Screen. Runs quiet and cool.
Cons: No back lit keyboard. Buying the extras (Ethernet, HDMI, VGA adapters & external slot drive). Price, would always like it cheaper, but it is reasonable when compared to other high end 13 laptops with SSD such as the Sony Z and Toshiba Protege 700.
Summary: I purchased the 13 Macbook Air over the Sony Z and Toshiba Prot 700. I am a business user that runs both OSX for personal and VMWare with windows for business. The apps I use are Office, Email, Calender, Web Firefox, movies, youtube, and casual photos and movie editing. Note I do not game. I ordered the 13 Macbook Air with 2.13 Ghz Proc, 4GB Mem, 256GB SSD, Ethernet adapter, hdmi adapter, vga adapter, external slot drive. I need the adapter for business presentations some conference rooms have HDMI to large screens, some have vga projectors. The Ethernet adapter is required for offices where primarily wifi is not available and the very rare hotel that doesn't have wifi or has both but wifi is weak/slow. The HDMI adapter works well at home with the TV for group viewing of movies, pictures, youtube, etc
This is by far the best laptop I have ever owned in my +15 years of using the laptops... it just works and is very fast providing a different computing experience, it boots is seconds, apps load immediately, the track pad is by far the best way to surf (if you haven't used it, go try it and see it for yourself), etc. The performance is excellent for all of my applications, including VMWare with windows running office, outlook, and Firefox. I am sure SSD and NVIDA graphics has a lot to do with the performance. Don't be fooled by all of the reviews about the old processor, it performs very well with excellent graphics and is plenty of power for 90% of the world. The size, weight is unbelievably light, but sturdy and works great in an office environment, especially for presentations and moving from meeting to meeting with 'instant on' as well as surfing on the sofa watching TV in the evenings. Although carrying the adapters is a little inconvenient, they don't take up much room in my brief case and it is a fair trade off for the size and weight of the laptop. You have to see it, hold it, run it on your lap to truly understand how the MBA is significantly better the build, design, size, weight is over even the smallest of high end laptops like the Sony Z and Toshiba Protege 700. The resolution of the screen is excellent, it seems that 1400x900 is a great fit for 13" factor, much better than my old Sony Zs. For the size/weight 2.9lbs the battery life is excellent and I have been receiving more than 7 hours for web/office and about 4.5 hours for video.
I am now using the 13 MBA as my primary and only computer. I just purchased a refurbished an Apple 24" display, which acts as a docking station for phone, power, printer, external hard drive. Note I also have a external USB hard dive for additional file storage for archiving photos, old files, etc. I prefer the idea of a single all-in-one computer, which just makes management so much easier. I have been think about an iPad version 2 if it incorporates printing and some other features, now with MBA I do not see the need for the iPad. Note I read on a kindle 3 and now amazon on MBA.
If you are looking for a light, sleek portable laptop that provides great performance for the typical business/home/student user (i.e. not a serious gamer or video editor or programmer that needs to do large compiles, etc) the Macbook Air is a great choice at a reasonable price if you compare other laptops with SSD. It can even act as your primary computer with minimal management/maintenance.
Final comment on the 11" MBA, I thought the screen was just a little to small to use for my needs and didn't think it could perform as an all-in-one computer. However, it is a great little traveler and would work well as a second computer for the road, including not having to take it out to be scanned in airports.
