I will be picking up a 13" 1.86 w/ 128gb SSD and the 4GB of added RAM. I intend on this replacing my 2007ish MBP, that is insanely slow these days (its the model pre unibody). I am hoping this will be sufficient for my sole computer, and during the holidays, I hope to replace my 23" Samsung glossy monitor with a 27" Apple display that should compliment the MBA very very nicely with the convenient power supply, audio and display port connections right there. I'm hoping it will be fast enough, and give me the ability to have an ultra portable laptop and then turn it into a desktop machine like an iMac-esque when at home. What are you guys' thoughts?
