Whether you buy a full-size sensored camera body or not, if you are pondering this question, you should stick to lenses that work on the full frame. They will also work for crop sensor bodies while you're on the fence. For Canon, for example, this means avoiding EF-S lenses, which are cheaper and lighter but only work on crop-sensor bodies..

I reckon this depends on your use for the pics. If it's just for "fun" and learning is it worth the extra cost to go for bigger sensor cameras...bearing in mind the additional cost of lenses etc...where if you are more casual and looking to learn maybe a small sensor is fine on a fixed lens slr. If you shooting stock and doing assignments then the larger sensored cams are probably better as they then pay for themselves.
Unless you know you need a full-size sensor (for instance you already have some expensive wide angle lenses that you want to work like they did on film or maybe you are a pro wedding/portrait photographer and you want to have a "better" camera than uncle frank) I'd just get a crop body and then you can use all the lenses, not just the film ones..
For my part I shoot with a canon 5D because I want my customers to have the best I can afford and I love the way I get a true 24 out of my 24-105. but stick the 17-55IS crop lens on a 30D/40D and you've got a good wedding combo. now I'm thinking about a camera like the 1D MKIII for weather sealing and the ability to write the photo to two cards at once for safety (I'd hate to be the one who had to call the bride and tell her that I couldn't read my CF cards)...
Thanks for the feedback. I just wanted to avoid investing in a technology that was being phased out...
I wouldn't worry about that. EF-S lenses aren't going anywhere and you can always sell them for a significant percentage of what you bought them for if you take reasonable care of them..
