I know: no one buys CDs anymore.

But at $4.99 a pop, Best Buy's collection of budget CDs might be a good way to fill some holes in your library for less than it would cost on iTunes. And remember, you can always upload the tracks to your computer. And let's face it: you need a copy of Abba Live, which would set you back $7.97 on Amazon. This offer is only good online, but my hunch is you wouldn't want to stroll up to the counter and buy an Abba album anyway.

Some other gems include James Brown Live at the Apollo 1962 and a bunch of Rush CDs.

Computer geeks and anyone else who wants to find a wide selection of accessories for their computer systems will miss CompUSA when its doors close at the end of 2007. It's mind-boggling how the richest man in the world, Mexican retailer and telephone baron Carlos Slim, could turn a multi-billion investment into zero in just eight years. In 2006, CompUSA had $4 billion in sales; that's expected to drop to just $1.5 billion in 2007 with more than 100 stores closed throughout the year.

In its heyday, CompUSA offered better protection for consumers who bought its extended warranties and better service than Best Buy ever could. While the service contracts will still be legally valid, I doubt the service will be anywhere near as good as it was when you could walk into a CompUSA store and work directly with the service people. CompUSA bailed me out of a number of computer crises over the years and I for one will miss them dearly. Luckily I'm married to a computer geek now who can do my repairs for me. My business would be shut down without my computer.

The biggest mistake Slim made was underestimating the need for marketing. While Best Buy and Circuit City fought it out for customers on the airwaves, CompUSA stayed silent. There was just too much noise from competitors and not enough response from CompUSA.

We'll miss you, and hope we can find another good outlet for computer accessories and support. For all the computer geeks out there that lost jobs as tech jobs moved overseas, this could be a blessing in disguise. It may be a good time to look into starting your own computer support businesses and replace the void CompUSA will leave.

Starting in February 2009, analog television signals will cease transmission in the U.S., as the transition to digital television should be complete. Actually, progress is heavily underway right now. Go into any store that sells televisions and good luck finding any without the digital tuners already included.

Stores like Best Buy and Wal-Mart will begin selling digital television converter boxes starting after the new year (February, to be exact) to allow American television watchers ample time to prepare for their destiny as digital consumers.

Here's an idea: instead of upgrading to new televisions for your home or office, why not save some dosh and bring home converter boxes? They will give your older, antenna-only boob tubes a longer lease on life. As an added bonus, the government will credit you up to $80 for your effort. Where's the downside?

Keep in mind, these credits are really only for the Luddites still using rabbit ears and roof antennas. Cable and satellite customers will be unaffected. Still, there's an estimated 13-21 million households that will need one (or more) of these boxes. If you have a large investment in a big-screen TV or a bunch or perfectly working older TVs, you'll need some of these boxes. They'll be widely-available wherever home electronics are sold.
