I was curious on the ratio of keyboard/non-keyboard android devices, so I did a little digging. I tried to remove phones from this list (source Droid Dog:
http://www.droiddog.com/android-blog...d-device-list/) that were either killed off, or have not been released yet (such as evo, legend, desire, etc), but if I made an error here, please correct. These are available right now, but not limited to the US.
Acer Liquid A1 - No keyboard
Acer Liquid E - No keyboard
Alcatel OT-980 - keyboard
Dell Ophone mini3i - No keyboard
Gigabyte GSmart - No keyboard
Google / HTC Nexus One - No keyboard
HTC Desire / Bravo / Passion / Dragon - No keyboard
HTC Dream / T-Mobile G1 with Google - Keyboard
HTC Eris (Verizon’s Hero) - No keyboard
HTC Hero / G2 Touch - No keyboard
HTC Magic / T-Mobile myTouch 3G with Google / Ion / Sapphire - No keyboard
HTC Tattoo / Click / Fiesta - No keyboard
Huawei T-Mobile Pulse Mini - No keyboard
Motorola Android Quench / Cliq XT / Zepplin - No keyboard
Motorola Backflip - Keyboard
Motorola Droid / Sholes / Tao / A855 - Keyboard
Motorola i1 / Opus One - No keyboard
Motorola Morrison / Cliq / Dext - Keyboard
Motorola MOTOROI / XT720 - No keyboard
Motorola MT710 - No keyboard
Samsung Behold II - No keyboard
Samsung Galaxy / i7500 - No keyboard
Samsung Moment - Keyboard
Samsung SHW-M100S - No keyboard
Sony Ericsson XPERIA X3 / X10 / Infinity - Keyboard
In summary,
18 without keyboards (17, if you combine the Eris with the Hero, which would be reasonable)
7 with keyboards
