That's just nasty, and potentially illegal.
It also sums up much of what I hate about Microsoft. I dislike anti-competitive behavior.
Apple's extreme of not wanting anyone to know anything about forthcoming products until they jump out of the magic hat fully-formed seems unwise in the present competitive environment. I wouldn't mind them throwing their weight around a little. Everybody else does.
See I don't think it's necessarily a bad thing if they actually have plans for that market and consider revealing them to be a good idea. I still don't buy the "everyone else does it" logic. I think words should be credible. If they mention something they intend to ship at a later date, they should ship something unless their plans change for unforeseeable reasons whether they're related to engineering, market conditions, or whatever else. Throwing weight around with no intention to enter a market hurts the smaller firms much more than the multinational conglomerates.
