Have had my Droid for only 3 days-haven't even begun to explore it's potential. Did run into that annoying (yet typical) PITA for users of Google Apps, because Google has still failed to create any kind of unified system. Thus I have my (paid Premium) Google Apps acct (which CANNOT be used in Droid Market,) my pseudo-gmail account using my Google Apps email address so I can seamlessly use Google products not available to Google Apps users (like Picasa, Google Checkout-but, btw, still can;t use that Google Checkout account) and a third Google account I created today so I could make yet another Google Checkout account and purchase apps from the Droid Store. Sheesh, Google, get it together!
Graduating to the Droid from the WWWM (Wonnaful woild of windows mobile) on a Motorola Q9c. As I do most of my stuff in Google's pieceof the could, it seemed a logical step. The above-mentioned Google kerfuffle aside, I like the tight integration with Google.
