Raptor hard drives are great, but having an increase of platter speed doesn't always neccessarily help applications... but I'd still prefer to have a raptor in my computer than any other HDD.
It's good to here that the storage sizes are increased, but I don't think it would help a lot... I mean you don't need a Raptor hard drive only to hold all your applications. It's all right to have a normal hard drive for most (all basically) applications, since you won't even notice a big difference.
Oh well it's good to hear that there's a bigger hard drive, but I'm not sure if a lot of people will be using this...
