It took more than two years after the launch of webOS for it to happen, but it's now possible to native edit Microsoft Word and Excel documents on a webOS device. QuickOffice HD has been released as a free update for all HP TouchPad owners. It can read documents from your email and sync with Dropbox, Box.net, MobileMe, and Google Docs. It's a bare-bones affair, but it exists and works well within webOS' card interface. Open your Software Manager app now to get the update.
