Yes, you did stir up a hornet's nest
My take - the older bd-ed3 is a LOT better feeling than the crappy BG-E2 grip that Canon are now peddling. There are posts about this on the forums. I think you'll find that, apart from the feel, the rest of the 30D easily out performs your older D60 (atrocious AF) and 10D (better AF but still not what I'd call great). As to heavy/light cameras, currently having a D60 (with the grip) and a 1D, there's no comparision to feel etc. The 1D wins hands down. The D60 feels light and plasticky. I'm sure the 10D will be better though, since Canon did improve the body etc with this model. The 20D body is pretty similar to a 10D in feel, but a bit lighter.
As to length of age of cameras, I'm pretty sure that the current crop of Digital SLRs won't last particularly that long. Today's modern age is a throw away society, and people have accepted this method of upgrading. Sad, but true. I'm not even referring to the number of shutter actuations either
When you criticise a Canon camera/lens on a Canon forum, you're going to get some active retaliatory criticism from the diehards, its unavoidable. I've had my fair share, since in the past I've previously made unfavourable comments about Canons marketing techniques and AF performance. I swear my 17 year old eos630 focuses better than my D60, and possibly the 20D. And I'm not even starting on the artificial price premium for a full frame camera. Of course, having posted that in the past, I got blasted, lambasted and made to look like a fool by some people. Not that I really care

All I was trying to say is that in my humble opinion my new 30D with BG-E2 grip doesn't feel as well built as my 10D or D60 with the BG-ED3 grip. As for the imaging, I'm hoping that the extra resolution, the spot metering and the larger LCD screen will justify my purchase.
And yes, I do prefer a heavier/lighter camera. Is there a problem with that?
My photographic days go way back to the early Canon SLR's when they really were built to last. And before anyone say's I'm a boring old fart, how many digital cameras will be around in 20 years time?
