To be sure, the Facebook fracas may put a near-term damper on tech IPOs from smaller companies and increase scrutiny on earnings results for the quarter.

"The bungled IPO has increased investor skepticism, and this means June quarter shortfalls will be severely punished and near-term hot IPOs more difficult to complete at astronomical valuations," said Canaccord's Davis. "But these are both good things."

The point is that ultimately, the Facebook IPO fiasco may mean that tech companies teeing up for IPOs this year, and their potential investors, will simply be more realistic relative to market conditions.

Out of the 173 IPOs in the U.S. over the past 12 months, 37 have been for tech companies -- more than for any other sector. And there are a number of interesting, up-and-coming tech companies preparing for IPOs this year. Companies mentioned by Davis and Fitzgibbon include firewall-maker Palo Alto Networks, marketing automation vendor Eloqua and SaaS provider Workday.

And while U.S. economic indicators have been mixed lately, they tend to start looking good in the months before a presidential election, Fitzgibbon said.
