This product is one of the worst designed, and most troublesomehandheld device I have ever owned.Biggest problems with it are:: The phone and phone features are an afterthought, and henceterrible in user interface design and usage.: It sucks up batteries so fast that I am going from chargerto charger: The power attachment, stylus socket are all poorly designed.I have lost 2 sylii, and have bought atleast 3 car chargers($20 each): The mail service (Treo Mail) is abominable. Now they'removing users to Visto, I hope it'll get betterThe only positive thing I have to say about this is that theaddress book integration &amp; sync to Outlook are pretty good.I bought it because it was heavily discounted, big mistake!!
