Does a smartphone really need a keyboard?

We're not sure we buy his argument that if it doesn't have a QWERTY keyboard it isn't a smartphone (in fact, we sorta reject it out of hand, even if we personally wouldn't buy a phone without one), but Stephen Manes has a good overview of the three new handsets with keyboards that T-Mobile has coming out, HP's iPAQ h6315 Pocket PC Phone (which technically has the keyboard as an attachment), Research In Motion's BlackBerry 7100t, and the Sidekick II.
