Did either of you read the post? The Treo hasn't set the world on fire. Like Riedme's post:
The Treo 600, now that's a Blackberry killer. You have to sell a lot of units, more than the competition to kill it. I don't think the Blackberry is even coughing at the site of the Treo 600, much less dying from its presence.
And do you really think that when Palm starts making these multiple OSs based on OS6 that all Palm software will work on all devices? Of course not. Try using Agendus without using a stylus. Or on a screen with ~100X200 pixels that is more likely to appear on a cell phone.
Also speculating, but I wonder if part of what is in this all new from the ground up rewrite (David Nagal's words, not mine) if they totally abandon OS4 code? I doubt they want a cellphone having to put up with the overhead of OS4 dragonball compatiblity.
