Make it a semi-smartphone like the N900 and you can count me in!

Yes, awesome.

And how about some of that Marvel vs. Capcom 2, eh?
Or Jet Set Radio?

Make it cheaper and improve the build quality, it's that simple.

Sure, you can give it all sorts of great stuff, the Snapdragon platform, 32GB of storage, 1GB of RAM, a 4.3" screen and whatnot.
But it'd be a completely different phone.

Yes, I'm still amazed by how you people consider the subsidised price the real price for the phone, and compare them as such.
Here in the Netherlands, you can get any phone for free on contract, the price of the handset depends on how expensive your contract is, so people start comparing the prices of the contracts for their full period.

An example: I got my HTC HD2 for 206 euros on a 1 year, 35 euros a month contract.
Now, I found this a much better choice than it for free on a two year 30 euros a month contract, mainly because I don't like to be stuck with the same carrier/phone for such a long period of time, but also because cost-wise, it was a lot better.
(By the way, this phone wasn't sim-locked in any way, so even though I got it on contract with one carrier, I could still switch to another, even during the period my current contract lasts.)

Lol, I remember having something extremely similair for my old Gameboy Colour! :D

I don't know how many times I have to repeat myself on this site:
The Snapdragon platform does have a GPU (Imageon Z430), and it's more powerful than the SGX530 in the OMAP3 platform, and only slightly less powerful than the SGX535+ in the iPhone 3GS, it has full OpenGL ES 2.0 support, and all the other important stuff.

Just an example of it's power, Soutend developed a game specifically for the Snapdragon platform, Electopia:

Now, a bit more on-topic:
I want Flash to die as quickly as possible, but it's good to see that they're at least trying to improve it.

True, those pics are gorgeous, the only smartphones that can beat that are the Idou and Omnia HD.

But apart from that, I'm not really interested in this device, my HD2 is serving me well! :D
Still, it's a great product, and it has re-established my faith in Sony Ericsson.

Turn it into an HTC HD2, it's a far better GPS navigator and a far better phone overall.

Eh, it's barely noticable, great contrast, and the colours are still pretty well saturated.

*Typing this from my HTC HD2*
(Sorry, had to do it)

Remote Desktop Mobile, FTW!

Also, how about:
-Multitouch
-Proper contacts list with groups
-Multiple exchange accounts

HTC solved two of these already, how come Microsoft can't do it themselves?
