The MBA is super-fast, mostly because of SSD. I want one! I tried my best to open 10 apps, 10 tabs in safari, play an iMovie video, and play a video in iTunes, in the Apple store, but I could not get a beachball to show up!!! On the fastest desktop they had in the store, it wasn't nearly as "fast" at least in this test. BUT- the drive space is small, and so I probably will be keeping my media like photos in iPhoto on an external HD, via USB. For those that are doing this, are there more beachballs or is it more sluggish when editing photos, or loading up iPhoto? It has to be, right? This could negate some of the benefits of the SSD and MBA. Thanks!
