A few readers reached out to me, asking whether Dell plans to promote its new Ubuntu systems. For a few days, Dell's home page promoted the systems on a rotating basis. Now, the PC giant apparently is using Google and Yahoo search terms to promote the new systems.

If you search the term "Dell Ubuntu" on Google or Yahoo, you'll likely notice sponsored links from Dell. Apparently, some eBay sellers are also using the "Dell Ubuntu" search term to promote their wares via Yahoo.

I'm hedging my statements by saying "apparently" because you never know who's truly placing all these adds. Hopefully they're from legitimate sources. But sometimes, as we all know, they're placed by rogue users... Buyer beware.
