I have to agree I do not have any issues at all with the Blur interface. Coming from an HTC this scaled down version of blur is a welcome. The OP will greatly enjoy the DX as it's one of the best devices on the market...
My issues blur are 3 fold.
1. It's REALLY slow. When/If you go the route of rooting and custom roms you will NOT go back. I run rubix 1.9 and my phone screams. For some though, rooting just isn't their thing. That's fine, LauncherPro is a good solution in that case. It will make your phone more responsive when you are in the home screens and the app drawer.
2. The bloatware that comes with blur is annoying and it does slow your phone down and it does take up space.
3. I would be much more tolerant of blur if they let me unlock the bootloader. I get moto/vzw wanna brand their products but let me un-brand something I own. Dell doesn't prevent me from putting Ubuntu or even Hackintosh on my laptop, why is OK for Motorola to try to stop me?
I'm a little bit idealistic, I know, and all that that being said, I would still love my DX if it still had blur, I just love it more now that it doesn't.
