Ahh I see!

2D-to-3D conversion software there are none yet but I wouldn't be surprised if some started to to appear soon (since there's suddenly a BUNCH of lenticular 3D screens on some Android phones and tablets demoed coming from HTC lately).

HD content playback isn't a problem, though--even my nearly one-year-old Samsung Galaxy Tab can do HD playback (even output 720p HD through the HDMI output) and ALL Androids have the ability to stream HD content to DLNA/uPNP compatible TV's and devices (I use my XBOX 360 to watch videos off my Droid and Tab sometimes, on my 1080p monitor).

Movie and photo enhancement software are APLENTY for Honeycomb, but I don't feel that there's any ONE stand-out killer app for that... and most don't do video enhancement of any sort and none of them do transcoding as far as I know... which I agree to be a big shame if tablets are to replace desktop or laptop computers for on-the-go video work or podcasting.

In summary, I'd say it's still early days for Android to replace a more serious desktop/laptop workhorse system like a Linux, Mac or Windows system. This is why I recently purchased an Asus laptop instead of just getting a Honeycomb tablet, when my old laptop desperately needed replacing. No tablet out there yet replaces them--not even Apple's highly regarded iPad2--but I think the Android tablets are CAPABLE of it already. The potential is there, we just need the software. They already have the horsepower (multi-core, high speeds), capacity (gigs of space and the ability to use hard drives) and the ports (USB, HDMI, etc.). Now it's just up to developers to take advantage of it.
