I was in the process of customizing a Tecra M4 tablet pc on Toshiba.com and encountered a couple difficult considerations. Since I'm new to the tablet pc world, I thought a few kind folks here could help Questions: How much system and graphics memory muscle do I really need? Should I "future-proof" (well at least for the next three years) by getting 128MB of graphics memory, or are 64 MB plenty? Should I go for 1024MB of main memory, or are 512MB enough? Situation: I'm heading off to get a PhD this fall. I intend to use my tablet pc for teaching classes (hook-up to projector and mark-up ppt slides, show video clips), taking classnotes, research, etc. I like Toshiba's laptops (currently on a Satellite Pro M15-S405) and want to step-up to a tablet pc after reading all the wonderful things about them. However, it'll also be my primary pc, so I need it to have some power for periodic video editing, gaming, etc., along with a larger 14" screen. Thus, the Tecra M4. Though it's a little heavier than most tablets, it seems comparable in weight to my current Satellite, so no big deal. Current specs of concern on Tecra M4 order: Pentium M 760 2.0Ghz processor, 512MB (will get from crucial, since $$ from Toshiba), 60GB harddrive (5400RPM), nVIDIA GeForce Go 6600 TE 128MB DDR SDRAM. Thanks for your advice!
