I def want more than 128gb's and the solid states are all crazy expensive still. Maybe once they go down in price ill pick one up but for now im stuck with the regular hard drive...I just dont know how much faster the 7200 will really be...I hear words like slower performance and better performance but just how much slower is it?
Switching from a 5400 RPM to a 7200 RPM, you'll probably feel a slight difference in speed. It'll be noticeably nicer, but still slight (i.e. start an application in maybe 5 seconds instead of 7). Going to an SSD from either is like a whole new world. Apps will start almost instantaneously (bouncing in the dock will almost be a thing of the past).
Of course, for just media, SSDs are absolutely useless unless you have insanely high bitrate media, since the rate at which data in most media moves is far slower than even a 5400 RPM drive can dish out. You'll see the most performance boost when you use a solid state drive to load applications and or use them as scratch disks.
Since upgrading from an HDD to the 128 GB SSD is only about $100 for the high end MBPs, it's a pretty good deal, even if you factor in the value of the HDD ($80 tops). So, you're getting a 128 GB SSD for $180, which is still maybe $40-50 cheaper than most SSDs on the market. You can then keep your iTunes and iPhoto libraries on a small external USB-powered hard drive, or even play the Optibay game.
Personally, I will actually be doing both. I'm going to order my MBP with Apple's 128 GB, and then Optibay the machine and put my own Intel into it. I'll install Windows onto my Intel drive, so that games will run better. No Boot Camp or partitioning needed. For OS X media, I'll keep it on a FireWire drive, and well, I don't plan on doing anything other than games in Windows.
