Question for the brain trust. Is it worthwhile getting a Flash RAM card for a PB and then keeping all your files on it? Here's my situation. I have a 1.67ghz PBG4 with 2 gigs of RAM - maxed out. I work as a financial writer/consultant and spend most of my time in Word, Excel, Safari, and Mail. I'll probably keep this machine until the Penryn update in '08. There's certainly no way I will upgrade before MS Office is a universal app. All the files & data I work with is well under 300 megs and could easily fit on a flash card. I'm wondering whether it would be worth it in terms of extending my battery life, keeping the machine heat down, and just having a backup of all my files. It seems like a cheap upgrade and a smart move, but maybe I'm missing something. I haven't heard of anyone else using Flash as their primary document and mail storage. And could I keep my Safari cache there? And would Tiger swap there? Any thoughts? Thanks.
