By the time Microsoft gets around to delivering Windows-based tablets, the market will largely be sewn up.
Microsoft has decided that Windows, not Windows Phone 7, will be its tablet platform, says Preston Gralla, a longime tech columnist. "That's a big mistake," he says. "Windows requires too much overhead and too much hardware to be well-suited for tablets."
Microsoft, according to a Bloomberg report, won’t release a competitor to Apple and Google’s tablets until 3Q2012.
