Senh: Looks just like the HD2, except with a better camera and operating system (Android). The only negative is that Sprint will be charging a monthly fee for tethering or using your device as a wifi hotspot, which you can currently get for FREE on Windows Mobile 6.5. If you think you're gonna be using this feature often, then I would stick with the HD2. Although tethering/wifi-hotspot is nice, I find that I actually don't use it much. Most of the time, I only use it as a backup in case my internet access goes down.
Dropbox has became an indispensable web development tool for me. It lets you share and sync files across multiple computers - your desktop, laptop, and netbook. It also keeps a history of your edits, like google docs. I use it as a poor man's svn to keep track of my edits to pages on Wopular, in addition to syncing design comps, and to-do lists. Since I already use my HD2 to pick stores to feature on the site, I thought wouldn't it be nice if I could also do some coding with it.
