I have my Touchpad just two days, and already have tablet-optimised clients installed for Twitter, Facebook, Box.net, an excellent video 3rd party video player for divx, and a comic book reader for reading my .cbr files. Combined with an excellent e-mail client and a Webkit web browser, I'm covered for my media and web browser needs.
The only thing missing right now is document editing, but that is due in an OTA update from HP which they have promised to deliver shortly (let’s hope they stick to these promises in order to try to restore some confidence in this very shaken webOS community).
So frankly as an owner of both a pre3 and a Touchpad, the whole "but webOS does not have enough apps" argument just does not ring true for me. If I want to do real work, I’ll fire up my PC. But as a web and media tablet, the Touchpad has me covered and then some.
