It goes without saying that a lot of tech stocks are much cheaper right now than they were at the beginning of October. But the amount of multiple compression that has been seen can still be pretty jarring when looked at up close.

In alphabetical order, here are 10 tech names -- some much bigger than others -- whose shares have taken a big hit and that are trading at pretty reasonable multiples now. For the most part, the valuations are based on forward earnings and cash-flow multiples. However, in the cases of companies whose near-term profits are depressed by aggressive spending, sales or billings multiples are used instead.
