Yuck
Really does go to show "you cant polish a turd". It seems any UI based on original stylus input needs to be binned as it just does not scale to multi-touch, and multi-touch seems to be winning the market (im no fanboi I loved my old Palm PDA but it wouldn't scale up work on "touch").
It will be interesting to see if the PC makers (including Apple) realise this when the make Tablets, will they try to squeeze a PC UI into a tablet form factor, or will they start form scratch. We will see (Firstly on 26th Jan maybe?)
