I ordered a base RMBP right after the announcement, as I've been longing for an IPS panel in a Mac laptop, but am having second thoughts. Geekbench scores see it only 50% faster than the top level MBA, at 10800 versus 7000. On the other hand, the RMBP is 50% heavier and bulkier. Do people know why the 4x2.3 GHz in the RMBP is only 50% better than 2x2.0 GHz in the MBA? Anyway, I'm reconsidering my purchase, given that I could get a top of line MBA WITH 512 GB SSD for the same price as this 256 GB RMBP. I just wish the Air had an IPS panel in it (high res is less important for me personally).
