Have had my ZG5 8.9" screen aspire one for a year now. Trying to revive it a little bit as I just recently wiped it. It is the 160gb XP version. AOA 150-1636 Model# ZG5 I want to: 1) replace 160gb HD with a 64gb or 120gb SSD (will any 2.5 sata SSD work?) 2) upgrade ram to maximum possible (recommend me memory please) 3) speedboost? something with using the SDHC cards? I heard about this from another thread, can someone please inform me? 4) install win7 ultimate (can i run x64, or is x32 recommended?) 5) any other upgrades I should do to keep this computer in top shape? I plan on keeping it around for a while since it's small enough to carry around everywhere! I would really want to keep this computer running quick for school work. thanks in advance.
