I know that the only thing holding back potential MB buyers is the graphics card. But really, how big is the actual difference between the GMA950, the GMAX3000 (the one expected in SR), and ATI's X1600? I doubt that the GMA950 will hold me back at all on day-to-day tasks but how about in the future? In two, three years from now, will it be too slow to keep up with new OS fetures? Or in a year or so, will it not be enough for newer games? I'm not sure if that difference is going to be enough to justify the jump in cost from a MBP to a MB or waiting until the end of summer(?) for a possible MB update.
