Nope, i don't have it. Deciding on buying it though... Anyway, I find that the best way to get info is to read full reviews Here's a non-biased review (the video tour in particular is great ) of the T2i compared to other competing models like the Nikon D90: [link]
I used to have one :] (T1i) it's a pretty great camera and wonderful to use! The range of DoF isn't as suitable for macro photographers though. But a great technique you can use to macro is to flip the lens, but that's also pretty dangerous cause it can get the inside of the lens dusty if you leave it out too long. I'd recommend this for portrait photographers, but as long as you get another separate macro lens really, anyone can use it ^^The auto-focus is great and so is the range of DoF they give you, but the manual focus is the best. It's a great camera for beginners, but if you're more advanced/professional in photography you might want to look at some others~ Whoa.. that was very long. I hope it helped!
It's a pretty new model... it's my first DSLR, and I really love it. I heard that the T2i had some pretty upgraded features in comparison to the T1i though. If you can afford to go with the T2i, I'd say do so.
Lenses that are from both the EF and EF-S series are both compatible, so if you've had a Canon before your lenses will probably work with this body too. ^^
