User Profile: After holding the wife back from updating her 13" Macbook because a CPU update is overdue to make that Macbook Pro actually deserve that "PRO" moniker. But that didn't happen so I got her a Macbook Air because I fell into the "I guess it's all she needs" trap but now that the blinders are off we're not sure if this is the right computer for her. Initial Impression: I'm a MBP15 user and I never cared about the original Air. It was overpriced and underspec'd so I admittedly went into this with only photos and commercials as a reference. From a consumer standpoint then the Air is a magically thin device that can get lost in a bookbag. I do believe all that advertising applies well to the 11" but since we're coming off a 13" Macbook then the wife and I were both surprisingly unimpressed with the MBA13. Performance: Overall performance is GOOD. SSD and 320M do a lot to hide how outdated the 2GB/Core2Duo is in 2011. Aperture runs sluggishly but it does run. The problem here is the non-upgradeable memory means that there is little future-proofing with this machine and that's a big problem. Size: The most interesting thing I found in real world usage is that there is a bigger difference between the MBA11 vs MBA13 than there is between the MBP13 vs MBA13. The MBA13 looks exactly like a MBP13 from every angle except it's profile so in terms of footprint then it takes the exact amount of space. So (regarding the 13") this whole "thin" thing feels more gimmicky than useful in the real world because plane/lap/desk usage will all fee the same with either 13" Macbook. Hardware: In typical Apple style, hardware is top notch in some places but handicapped in others. I'm obviously not a fan of C2D in 2011, but the lack of backlit keyboard and the .3mp camera are ridiculous for a "Premium" product. The biggest deal here is SSD which I'm now considering for my MBP. Pricing A lower price is nice but let's be realistic. These pricepoints are more about cannibalizing sales than being fair. And based on this article then the Macbook Air is now their most profitable system. Weight: Most adults can carry a 3, 4 or 6lb notebook one-handed with ease. So it really comes all down to how heavy a computer "feels". Many cheapo netbooks and the 11" Macbook Air "feel" lighter than 2.4lb because the footprint is so small and the weight distribution is minimal. But because the MBA13 and MB13 share the same footprint then carrying an open Macbook Air around surprisingly felt as heavy as our old notebook. Battery: 5/7hrs on the 11/13" MBA is contradictory towards what these machines are aimed to do. These are ultraportables using outdated processors with no spinning drives yet the MBP13 has a far superior 10hr battery life. So for travel then it's tough to say that the Air is Apple's best travel machine. Final Verdict (PERSONAL OPINION): We still might keep it because it's so darn cool, but in comparison to a C2D Macbook Pro 13 then the ONLY thing that the Macbook Air 13 does better is fit under a bathroom door. My recommendation is that the Macbook Air 11 is a fantastic machine that is unique in Apple's lineup and worth the premium price. BUT, if anyone looking for a Macbook Air 13 should HEAVILY consider the Macbook Pro 13 instead.
