Senh: It's already available on Windows Mobile devices. I guess if they put it on iPhone and Android devices, then I'm sure it's gonna be a hit. It's just whether or not Microsoft want it on competing phones.
HTC's Sense UI runs on top of Windows Mobile 6.5 on the HD2, providing a better UI and convenient shortcuts to Windows Mobile apps. It's finger-friendly and hides most of WM 6.5's software and interface flaws. Sense UI is a slick and mostly well thought-out interface, but it has a few shortcomings of its own. On the home tab, the first screen you see when you power up the phone, the quick links to your favorite apps are limited to nine; the calendar contains only one entry; and there's no task list. Co0kie's Home Tab (CHT) fills these voids.
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.
