The slowness is the memory card. I have a Focus with a high end memory card and it's great. WP7 software RAIDs (kinda) the SD card with the internal flash and treats it all the same. One nice thing about it is that unlike my Nexus One, all storage is first class storage. Apps, music, photos, video - All of it can go anywhere, with no special casing. The bad thing is that if your SD card is slow, everything is slow. That said, Microsoft should have known OEMs would expose the card slot, and that users would put in slow cards. They should have gracefully handled it, or had the OS ignore/reject crappy cards, like they did with ReadyBoost on Windows.
