I went from having a 17" Mac Book Pro core i5 and a Mac Pro 8 core, both with maxed RAM to my MBA 13" top of line. While I love the SSD, and I love the form factor, when working at a desk I really really pine for more RAM and a faster chip. I push the machine super hard on a normal day, not even when doing development. Now as a portable, nothing can beat the thing, and when working on its 13" screen, it forces you to edit your multitasking so you really don't push it as bad. But when hooked at a 27" screen, you are tempted to multitask more and it gets bogged down. Next week when the new iMacs come out I'm going to probably get one of those to use as a desktop machine and use the MBA as a portable. With Dropbox and MobileMe and Google sync, this is an easy proposition.
