Higher resolution in the 15" is a waste of money in my opinion. Text simply looks as if the viewer has shifted back his viewing position by a couple of feet. Why pay for that dubious "benefit"? Better to put the money towards a size of screen that benefits from the extra resolution, like the 24" Apple Cinema Display. I had a 17" MBP with high resolution and even that made most content look annoyingly small and I was constantly enlarging stuff. The 15" will be even less suited to the high resolution "upgrade", going by my experience.
