I never said Apple invented the Tablet James, they rarely invent things - they re-invent things, specifically for Mass consumption.
I myself bought an HP Touchsmart Tablet PC (with Multitouch and a 12" screen) BEFORE the iPad, for our Song Charts at Gigs.
At that time, (about 12 months ago) there wasn't much of a choice - and you don't wanna know how much I paid for it
NOW
We have Tablets coming out of our collective orifices, either available right now, or coming soon - all with many options, and all with a significantly reduced Price Tag from when I bought our little wonder....
