I just upgraded my computer to 4GB. I got new Kingston 2GB 800MHz RAM on ebay for 32 AUD, which was under half the store front price these days, and about the same price as before prices went up.
Also there are a couple of good deals on Netbooks today, a 10" ASUS D250 for
$470, and the original 7" EeePC for
$270 including shipping, although $270 is about what I bought my EeePC for in Thailand.
