I had a TouchPad for about a day last week - I now work for HP and internal colleagues got first dibs on the last batch that were made.
For the price (£109 for 32GB) it is fantastic. I have an iPad though so sold it (same price) to a colleague in HP. I wouldn't have paid full price for one though. The software still needs a little work - sometimes it was laggy on swiping and boot was very slow.
It did run flash though, dd. But it was, invariably, rubbish on a touch screen. I went to a flash games site and it couldn't work out what I was doing as it was expecting mouse clicks not touch. Another reason I hate flash.
People here are waiting until Android will run on it so they can get the apps.
