Hello all. I am definately buying a pbook soon, and i have some questions for pbook owners. Is the faster ram, better graphics card, faster processor, and bigger screen worth the extra $500 - $700? I will be carrying the laptop in my backpack most of the time, so is the 15 too big for this? Also, anyone with a 12 annoyed by the 1024 X 768 res.? I think that would bother me after a while, as I usually run 1280 X 960 on my emac. But I figured actual owners would know better than I. Please, only owners of the new pbooks need respond. thanks.
