Having done a bit of Googling over the weekend, I found that the new toy I so eagerly crave is available as a free download from Microsoft for TabletPC. Unfortunately it will not work with a non-tablet PC.
Or so I thought.....
Further Googling revealed that the source code is apparently freely available and that with a wee bit of jiggery-pokery it can be made to work with a non-tablet PC. I'm no programmer, but one of the school IT technicians (Bob) loves a challenge, so I've delegated him the task (or should that be derelicted my duty) to find a way to make it work.
Watch this space!
Or, if you too relish a challenge, follow these links -
(First download needs validation, second doesn't, not sure if they're different.)
If anyone reading this does make it work, please let me know how you get on. Good luck!
