4GB RAM is mandatory for MBA.
I totally agree with you about 4GB RAM.
I totally agree with you about 4GB RAM.
From my experience with a November 2008 SSD model (1.86GHz), the SSD helps on reboots (it takes about 12 seconds and is almost "instant on" from sleep), and launching of programs. The SSD won't really address performance issues on write-intensive or CPU-intensive tasks. That said, my biggest complaint about the old Air was their limitation to 2GB of RAM. I'd highly advise anyone getting any model to get 4GB RAM. Safari slows to a crawl with 2GB if you have more than 8 or 9 tabs open.
