That refurb offer looks like a fantastic deal. I was waiting for WWDC, but even if there is a bump, I'm not convinced the bump will justify buying a speed-bumped system rather than buy one of these refurbs now. The saving is incredible. I was actually comparing the refurb prices against the UK Higher Education prices, and even with the new systems already discounted by approximately 15%, the refurbs still came out about £280 cheaper!
I've bought this one: Notably it comes with the 256MB Graphics RAM rather than the usual 128MB, and a single 1GB SO-DIMM rather than 2x512MB 😀

If WWDC heralds greatly improved MBPs, then I'll return the refurb and buy one, but I'm seriously doubting there'll be anything to justify paying £280+ for.
