The tech industry's answer to this week's stock market roller coaster was delivered on Tuesday by the mighty Apple Inc.
Apple saw its stock price rise enough -- gaining more than 5 percent -- that it briefly surpassed Exxon Mobil, as the most valuable company in the U.S., according to an Associated Press analysis of its market cap. (Exxon Mobile wound up the day slightly ahead of Apple.)

Most of the other major tech companies -- Intel, IBM, Dell, Microsoft, Hewlett-Packard -- all finished in positive territory yesterday, as markets made up ground lost in the big sell-off on Monday that also hit oil prices and other commodities.
Maybe yesterday's rally was all that's needed to shake away, at least temporarily, some of the economic concerns the IT industry still faces. By closing in on Exxon, Apple effectively affirmed that there are few limits to the tech growth.
But more immediate trends are worrisome. Recent events, including debt problems in Europe, the U.S. credit rating drop and earlier market losses, have begin to raise fears that consumers may retreat and CIOs might start cutting IT budgets.
"Until last week, there was really no worry of a downturn in tech, at least not here in Silicon Valley which has been very healthy this year," said Charles Wuischpard, the CEO of Penguin Computing, a privately held HPC firm that has had a good year so far.
"I think it is too early to say whether there will be a sustained impact, but certainly in the short term, we are naturally more cautious about hiring and spending until we have better visibility into the trend," said Wuischpard. "And that's the danger, really; that everyone shifts into a cautious position and the threat becomes the reality."
The trends for tech in some areas such as initial public offerings (IPOs) are nowhere near as bad as they were three year ago.
In early 2008, one sign of a troubled economy was the drying up of the IPO market. By the time Lehman Brothers collapsed, there had been just six venture-backed IPOs that year.
In the first half of 2011, there have been 36.
"This is not 2008, for sure," said Mark Jensen, partner, Deloitte & Touche LLP and national managing partner for venture capital services. "The economy has been improving, [though] not as fast as people might like."
Though economic conditions are more solid than in 2008, Jensen remains concerned that market turmoil will have the same kind of impact as three years ago, "which is the uncertainty just starts to bring everything to a halt."
Andrew Bartels, an analyst at Forrester, still believes the odds favor "really weak, but still positive, growth" in the tech sector.
But if CIOs start cutting, they will follow the steps they have used in the past: First, cancel purchases of computer equipment, then look at what projects can be deferred. Contractors might get cut, contracts renegotiated and -- if it gets that far -- layoffs, said Bartels.
The impact of the 2008-2009 recession on hardware spending, in particular, was pronounced.
