I've had the T1i for about almost week now and after some extensive use, here are my thoughts:

1. 15.1 megapixel sensor. Yes, the high megapixel count is impressive, but keep in mind that, as you approach higher resolutions, you need to ensure the lens on the SLR can resolve that much detail. Sadly, the included 18-55mm IS lens is functional, but the high resolution really shows the so-so quality of the lens. Even if taken at the proper focus, pictures can appear soft with this kit lens. Shots I have taken with Canon EF-S 17-85mm and EF 70-200mm L lenses are crisp. I don't have any gripes on image quality. There are some issues with noise on the higher ISOs that don't seem to show up on the Nikon digitals, but overall, the quality is amazing for the price. Skin tones, textures, colors are reproduced very accurately.

2. Digic 4. The Digic 4 processor appears to process/save the 15 megapixel images in the same time (if not faster) than the Digic III processor on... Read more

Here's a quick, first impressions (from hands on shooting) of the Rebel T1i. Although we'll need more scientific examinations to determine ultimate image quality and usability, I'll try to give a hint into the camera's potential.

I'll not go in to any real detail on the kit lens, which has been well reviewed. Let's just agree that $100 for a good quality IS (image stabalized) lens is a very reasonable value it you don't have another option. There are no obvious reasons this kit lens should make or break your choice of this camera over a competitor's.

Styling and build wise, the T1i is an XSi made over, which is not a bad thing. Some found that camera to be a bit on the small size for their hands, or a bit lacking in weight, but most like the size and weight (include me). It uses the same, proven battery and accessories of the XSi. I've already used some generic batteries that worked well in an XSi, with similar good results, but I do not want to lump all...

**see update below, now give this camera a 4 star
**** Video Test memory consumption rates and max minutes per clip contained below.

I couldn't wait to my hands on the new Canon T1i. It was a stretch for my budget but had most of the 5d mkll features. I was excited. I pre-ordered a body (I already have 2 xti's and lenses) but the only the kits are/were available so I upgrade to get it before a SciFi convention I attended.
Higher iso and video, for the less than optimal lighting in the hall where the Celebs were speaking, attracted me.
I tested the video for memory consumption rate the day I got it, no problem for a 20 minute test run. I saw a little white bar on the right side of the screen appear get a little bigger, then disappear. I figured it was a buffer level. Next day at the convention during Jeri Ryan's appearance I took a few stills and flipped into the video mode, nice.... until it stopped after a few minutes. Set it back up, pushed record again a...
