Hi folks! For about a week now I have been a happy owner of a base 13'' MBA. I have been a reader (lurker) of this forum for about the same amount of time. One of the things that I see come up a lot in these threads is the fact that people are worried about the MBA being able to handle certain tasks. In particular, a lot of people seem to be interested in using the MBA as their "main" laptop/computer. [Edited for clarification] My opinion on this is as follows: If you are looking for a solid laptop capable of handling your daily grind at work or school and you are interested in the MBA, then the MBA is a good choice for you. I offer you my experience with my base 13'' MBA as evidence of this. Earlier today I shot a 12 minute clip of 1080p video for a hobby of mine. The video ended up being about 2.8 gb. I copied this video to my MBA and proceeded to edit it to my liking (nothing fancy, just added a couple of titles, transitions and a song) in iMovie '11. The final product was a 4 minute long 1080p video. I was able to "finalize" my project (create 1080p, 720p and other qualities of video that this process creates) and upload it to youtube in under 30 minutes. That's 40 seconds to copy the original clip to the laptop, ~28 minutes to "finalize" my project and ~2 minutes to upload it to youtube in 1080p. While doing this, I was able to comfortably browse these and other websites. Things to consider: The computer DOES get quite hot. We are talking about a core temperature of 90-93 degrees C at its peak. This was before the fans kicked in. With the fans, the temperature was kept at around 78-81 degrees C, which seems pretty reasonable. (Fans were at 6400 rpm at their highest. I have iStat screenshots if anyone wants to see them!). The laptop was certainly warm on the bottom but not hot - "you could keep it on your lap" temperature (unlike my old HP laptop, which would be too hot to touch). Of course, you must understand that what I have done isn't anything truly taxing as far as processing power goes. Just a short clip in iMovie. But let's be honest, for an ultraportable laptop this is about as taxing of a task as I would consider. For me, things like gaming are handled by my desktop. I use my MBA for work and school. Things like having multiple windows for programming open while also having multiple webpages open and music playing/streaming are handled smoothly by my MBA. And now, having worked with iMovie, I would say that my experience with my MBA has left me very satisfied. These updated models offer enough processing power to get me through basically anything I would want to do on a laptop while offering fantastic portability and looks. I hope that this was a worthwhile read. I also hope that I have been able to offer helpful information to those of you hesitating to pick up an MBA based on processing power. Thank you for reading. Take care!
