I'm thinking about upgrading the HD in my PowerBook, and am wondering if 120GB is he largest available. I've searched for 160GB drives, but all I can find is press releases stating that they have been developed by various manufacturers. Any ideas as to when they'll reach the market? I just don't want to go out and buy a top of the line 120GB drive when 160's will be out in a matter of days/weeks. However, if 160GB drives won't be out until sometime 2006, I'll go ahead and get a 120GB now.
