Tuesday's sell-off may have been a classic case of buy the rumor/sell the news -- heightened a bit by the president's anticipatory remarks at his first press conference on Monday.

Whatever the reason for Tuesday's sell-off, it will no doubt terrorize the public and have the letter writers running for even deeper cover.

While Research In Motion (NASDAQ: RIMM) and Apple, Inc. (NASDAQ: AAPL) are locked in their battle for smartphone supremacy, a new entry into the market has grabbed headlines.

Palm's (NASDAQ: PALM) brand new touch-screen smartphone -- the Pre -- was the surprise event at this year's Consumer Electronics Show (CES). Among other things, the Pre uses the Palm's Web OS, which supposedly can consolidate data from multiple Web sources.

The canary in the coal mine for the economy is business capital spending.

IT spending? What IT spending?

According to ChangeWave Research surveys, spending is flat or falling.

There are no gee-whiz products to buy and install, the number of employees is shrinking, meaning there are lots of extra computers and spare server capacity lying about. The number of licensees for a software license is shrinking and so on.

What's worse, IT spending is contracting even faster overseas, and these markets account for more than 50% of the revenue for most big U.S. tech outfits.

A recent ChangeWave smartphone survey of 3,800 cell phone owners measured customer reaction to Research In Motion's (NASDAQ: RIMM) newest touch-screen phone, the BlackBerry Storm.

The survey was conducted just weeks after the Storm went on sale.

We also compared the Storm's favorability rating to those of the original Apple (NASDAQ: AAPL) iPhone, taken from a 2007 ChangeWave survey conducted a few weeks after the iPhone's release.

The original iPhone's "very satisfied" rating (77%) was more than double that of the Storm (33%).

Moreover, the original iPhone's unsatisfied rating (5%) was three times lower than that of the Storm (14%).

Dropped calls have been a nuisance since the dawn of cell phones. But which cellular service provider has the best record in terms of the fewest dropped calls?

In a recent survey, ChangeWave asked 3,800 cell phone owners to estimate the percentage of their calls that were dropped during the past 90 days.

The survey, which was conducted Dec. 9-15, 2008, produced a clear winner: Verizon (NYSE: VZ) has the fewest dropped calls of all.

After the stock market meltdown of 2008, Wall Street brokerages aren't anyone's favorites in 2009.

But some customers said they're still happy with their online broker.

A December ChangeWave survey of 3,051 consumers found that despite the extremely difficult financial market, two online brokerages still capture high customer satisfaction ratings -- Charles Schwab (NASDAQ: SCHW) and archrival, Scottrade.
