We had Windows 3.x table pen computer prototypes way back in the early '90s in the labs at Lotus and MS never did anything interesting with the technology all of these years until the iPad comes out and suddenly they're falling all over themselves to get it to market.
HELLO? ANYONE HOME AT MS? 20 YEARS TOO LATE!
Why in the heck would they take such a massive technological lead and just flush it I'll never know.
I'm in agreement with you Bill. They really squandered this entire market. I'm not sure how or why. Bill Gates was really hot on the tablet form factor for years when he was at the helm. It's only now that we're seeing old clips of him talking about this with Steve Jobs, etc.
