If the N900 got rid of the physical keyboard and went for a screen like on the HD2 I dont think I could contain myself.

With that said, there are clear advantages I can see to the HD2 over the N900, however, you read on and it's Win Mo 6.5 and there's feck all memory. HD2 certainly seems like a pretty nifty smart phone, but I really want more than a smart phone, so i'll go with N900
