Not sure if cats have read/heard about this yet, but just about the time that I was looking to upgrade the HD in my unit, IBM throws this at me. Whoa... a 7200 rpm HD for the lap? I just got back from a retailer, and the sales guy told me to wait til the new year. Regardless, I'm thinking heat dissipation issues and serious batt drainage. Outside of that, could be fun. Looking for competing units from Toshiba and others hopefully... IBM likes to drain pockets. Oh yeah, the 80G unit? @ 9.5 mm? That's serious too. Scared to ask price though.
