Hey, Ayla How are you?
I agree with Q on not relying on the waterproof material. I've had some problems where the waterproofing has failed on me and I had wet papers Get some kind of extra cover if you expect rain. I've also been very fond of Targus bags and backpacks for my electronics over the years. I cant say enough good things about them.
The cpu socket makes it so you dont have to worry about die size. A socket FS1 is a socket FS1. Always. As far as I'm aware, the upgrade shouldnt be a problem unless Toshiba did something to lock the laptop into only being able to use one processor. But we rarely see stuff like that from Toshiba, so I dont see a real problem.
When I was told "new Bioware franchise" I never expected them to have C&C Generals thrown at them. I dont have much faith in this title. Bioware doesnt have experience in RTS games. Plus EA is usually too focused with bringing over the top visuals.
