Olympus and Pentax offer DSLR's that are maximized for those moving from the P&S world to the DSLR world and their designs reflect that.
That is insanity. I have to assume that you are speaking out of lack of knowledge rather than true information. Do you really think that the K20D and the E3 are built for PnS people?
And if the Pentax and Olympus cameras are built for PnS migrants, why are the Pentax DSLRs the only ones that have a top LCD on
every one they've ever made (ditto spot metering, DoF preview, etc) including their cheapest entry-level models? Why do only Pentax and Olympus offer a "proper" kit lens (read: metal mount, stand-alone focus ring, non-rotating front element)? Why is Pentax's new entry-level weathersealed? Why does every Pentax DSLR work with
every Pentax lens ever built including medium-format and screw-mount lenses? Is this the way you design a DSLR for PnS converts?
Look, there's nothing wrong with cameras targeted towards people moving from PnSs. That's what many entry-level DSLRs are targeted to. But c'mon. Your claim 1) seems to denigrate a PnS-friendly design and 2) indicates that this is the domain of Olympus and Pentax. Look at the D40 (and D40x and D60) - those are DSLRs specifically designed to appeal primarily to people moving from PnS cameras (complete with "help" screens), and are marketed as such. ("Anyone can take great photos.") And yes, Olympus has chased the market somewhat too with their Live View implementations, but they have had higher-line DSLRs all along that play in a higher market - and check out the new Sony line, no less than three entry-level DSLRs designed to appeal to PnS buyers - especially the A300 and A350, designed so that PnS converts never have to use that pesky viewfinder.
How did they do that with the superior technology of the Pentax E series, Olympus K series and Sony Alpha with their in camera image stabilization? Marketing and lens, lens, and more lens.
Ummm... Olympus is "E" and Pentax is "K". And only the relatively new Pentax DSLRs are K-series, earlier ones used the (terrible) *ist prefix.
Forget the fact that even the Canon XTi outperforms the D40 every which way you can think of
How's that spot metering on the XTi? Oh yeah... doesn't have it. Good thing that C/N don't build cameras designed for people migrating from PnS cameras.

Then there's the kit lens, ergonomics, build quality, etc...
C'mon. Coming in here and being dismissive without knowing what the competition is up to is 1) troll behavior, 2) insulting, and 3) reflects poorly on yourself more than anything else. You obviously hate Nikon and love Canon, and this kind of behavior reflects poorly on Canon fans. The D300 is a pretty amazing camera yet you can't think of anything positive to say about it? They are
cameras - we're not discussing politics or religion here, y'know.
Oh, and as for "gathering dust", Pentax has had zero problem selling all the DSLRs they can make, and the K100D Super and K10D disappeared very, very quickly when they were taken out of production a couple months ago. They also sell more than Sony or Olympus despite not being in the "big box" stories like
Best Buy, Office Max, wholesale clubs, etc. They're not
trying to be C/N, they compare themselves more to Subaru, who don't try to out-sell Honda and Toyota - they don't to build a car for everyone, they build a car that's perfect for those that buy them, and have incredible customer loyalty as a result. So Pentax is selling all the cameras they can make and have a happy customer base (who they listen to when designing new cameras) - sounds good to me.

Before I posted the question I had been considering the K20D, and the a700. In the end I weeded these out due to Sony's high cost of glass, and the K20D due to the fact that should I progress to a professional level I am not sure if the body would support that. (The K20D decision was purely based on speculation though)
Speculation indeed.

The K20D is IMHO certainly more pro-friendly than the A700. The K20D can capture more resolution (actual detail, not just # of pixels) than any other APS-sensor-sized DSLR out there and has image quality rivaling the full-frame DSLRs and high-ISO performance that's as good as the D300 from what I've seen. It also has some of the best lenses you can buy - their line of primes are usually the best in class, especially the Limited line. The only real "issue", if you can call it that, is that it doesn't have the full machine-gun continuous shooting speed of the D300 (and to a lesser extent, the 40D) but then again, it's shooting larger photos - and if you set the D300 to capture 14-bit RAWs, it drops to only 2.5 fps. Then again, the K20D does give you a 21-fps mode but without focus/exposure adjustments and at a much lower resolution. Very cool but useful only in certain situations.
Based on your original question, though, I'd definitely go with the D300 over the 40D - even with the extra cost, and put a proper high-quality lens in front of it in order to get the best performance. Congratulations on your new camera! The problem now is that you can't blame the camera if you get some lousy photos.
