Less bounce for the buck!
If you have a dose of Alpha-mount lenses, upping yourself to an α700 from the α100 or α200 is a wise and clever choice. Non-SONY users (except for Samsung/Olympus and Pentax) cannot appreciate the wonderful convenience of anti-shake with EVERY lens, as the SONY crowd does.
Video is a novelty ... and anti-shake ... a realized asset. Just ask some Canon user whether or not they enjoy it in their ... larger zooms and PRIMEs. Just imagine how nice it might be in ... oh yeah, EVERYTHING! ;)
Confrontation misdirected ... get the bargain!
I am a bit confused about your side of this simple proposal, as the α700 was developed long before (like 4 years) the advent of DSLR video. It is holding its own, still (as decent stuff usually does) and now can be had for a chilling price of only $850 (42.5% of its "Full Frame" big brother, the α850)!
I mean, all the introductory camera folks can get total prosumer DSLR capability for just a couple hundred more. You want video, buy it ... but don't cry about it not being in a four-year-old, excellently designed camera.
C'mon ... :p Some image takers are seriously going to benefit from this bargain pricing. Not everyone is interested in making movies and having to struggle with capacity and splicing! I think you need to pick your contests better. This one is not the place.
A700 ... it's a solid choice
Yep ... only SONY. Why bother with the rest?
If you are using Nikon glass ... you have the Nikon and Fujifilm option
Canon glass ... Canon bodies
SONY/Minolta glass ... SONY bodies
Pentax lenses ... Pentax/Samsung
Olympus .... well, you know.
You know, if you have forgotten which forum you are in ... just look near the top of the page. It is kind of self-explanatory.
