Im not in the market for a DSLR right now, quite happy with the IXUSii & the 35mm. But as consideration, if I could use FD lenses on a DSLR I would get a Canon. But as I can't use them, it has slowed my enthusiasm to get anything above the IXUS, I use this quite a lot. It does take very nice photos & is small enough to have with me all the time. So when it comes to that point to go DSLR i don't feel tied to Canon.
Anyway I'm a bit slow on the take up on new ideas in photography, I was using the F1 exclusively until 3 years ago, before I ventured in to the crazy world of auto exposure & motor-drive with the A1. So I might wait a while to see if this digital fad catches on before i get involved
