Well I would grumble as I owned a MBP 15 with the 2.16 and 7200 RPM drive until yesterday. I was really bumed out my wife lost her job on Friday so I took it back since it had not been 2 weeks. The manager was nice enough to wave the restocking fee since I told him I woul dbe back in a month or so once my wife could find a new job.
Strangely enough I joked with him and my wife about, ahh I'll just get the 17" next time. This morning I strangley feel better even though I am currently mac less. The MBP 17 is 100 less then the load 2.16 15

I wonder if the battery is bigger?? And if it gets better life I loved the MBP 15 but it got about 3.5 hours with the way I ran it..
