There are four primary things people initially use their tablet. I will list what I use. You may want to look at other solutions for video. The ZT-180 is not as advanced unfortunately.
Book Reading- IReader, Adobe Acrobat, Chymreader
Internet browsing- Default browser, Opera 5.1, Skyfire
Games - UnblockMe, Monopoly, Angry Birds
Videos - Rock Player, Meridian and using the MediaCoder as the transcoder to make the movie viewable when needed.
I also do Internet radio Listening using - Tunein Radio
