Intel used to sell modems, the most expensive Fax modems ever made ($400-500 each). One day (1994) they dropped out of the market, stranding all their users without drivers for Windows 95, 98 or any OS beyond that.

I would buy any major brand other than Intel, at least for a few years. They could decide one day that they can't make a major profit in either of those areas and fall back on their processors again.
