I just wanted to share some good news - I upgraded the ram in my 15in pb today from the stock 512 to 1gb, and it has transformed it. I know I'm sort of stating the obvious, but I've had this thing a week and was on the verge of returning it- it has the lines thing, which i feel I can deal with, but it was so sluggish and laggy in general use that I didn't feel at all like I'd bought what is supposed to be among the fastest laptops currently available. I do a lot of flash and design work, and since I was migrating from a dual processor Pentium 3 pc, I was expecting massive improvements which unfortunately didn't come. I'm happy to say that the Ram upgrade has improved things a lot, but I think it does raise questions as to the performance of the pb out of the box- if it can't perform to an adequate level with the stock memory, shouldn't they be bumping it up a bit? I know ram upgrades always help and there is an option to upgrade upon purchase, but in my opinion the performance with the standard 512mb is simply not up to par. Anyone else agree?
