The just announced HTC Touch HD is now available for pre-order on the German Amazon web site. They list the price as 619 Euros (about USD$890).
Interestingly, the Sony Ericsson XPERIA X1 is also listed. For 639 Euros (about USD$920), you only get a 3.2MP camera, lose the global HSDPA connectivity (the Touch HD is only dual-band HSDPA), but gain a slide-out QWERTY keyboard.
You have a bit of time to do your pros-and-cons list for each device as Amazon does not provide availability dates for either device.
