I bought the XSi a little over 2 weeks ago, and am loving it. I upgraded from P&S the canon powershot XS100 IS, and while that was a nice cam with a nice zoom, this DSLR trumps is hands down obviuosly. I got it with the 18-55mm lens, which is nice, the IS is awesome, can shoot at 1/30 no prob. RAW of course is great, which most P&S dont have. i definately remoent the XSi as an entry DSL, worth every penny.
I'm looking to buy the XSi. I'm curious to see if anyone has used it and what they thought of the camera.
