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.
Ever since I saw the specs on HTC's HD2 several months ago, I wanted to get it - 1GHz processor, 5MP camera, and 4.3" screen. You see, my contract with T-Mobile then was done, so I was looking for a new phone to replace my ancient T-Mobile MDA. I had that phone for four years which, in cell phone years, is a lifetime.
