Yes, my Danger Hiptop arrived today. I celebrated by posting to HiptopNation. I already have a wish list of features for the Hiptop, like the ability to use iSynch for my calendar and addressbook. The boxmodel is not so pretty on the Hiptop/AvantGo browser.
I am happy with my purchase as I now have the ability to have my information follow me easily. The mobile e-mail is a great tool. Yes I know Blackberry has this funtionality, but the price and other added functionality, including phone was far more enticing. The form factor on the Hiptop is very inviting to the hands, although the thumb-fu has my bad thumb kinda wanting a rest.
I may build an administrative interface for Off the Top that I can use in the Hiptop and other mobile devices.
