I have been itching for a Treo ever since the 600 came out and I noticed that more streamlined design.  When smartphones were first introduced, I bucked the trend of combining the two thinking that as often as I use my cell phone and my pda, if I bought one that integrated both I would wear it out twice as fast.  And in my humble opinion, it was a valid reason because back then, the original phone/pda's were impossibly large.  Well I have finally become a convert.
