Handspring has posted a sneak preview of the Treo 600, a palm-based phone with a keyboard, color screen, color camera, and SD slot in a small package (and no flip cover!)

I'm realizing more and more that my Sidekick isn't very good at being a phone, though it rocks on email and instant messaging. I've got to figure out what my long term plan is: getting a phone and using the new data-only option for my sidekick? Ditching my email dependence and dropping the sidekick altogether? or maybe a different hybrid, like this Treo.

Luckily, the Treo 600 doesn't come out until this Fall, so I've got plenty of time to mull it over.
