Dell today flipped the switched and is now officially offering consumer desktop and notebook PCs with Ubuntu 8.04 pre-installed. Two notebooks and one desktop join two desktop systems in Dell’s open-source product portfolio.

Dell has told DesktopLinux.com that it will be announcing later today, Dec. 19, that it will be releasing PCs with Ubuntu 7.10 (aka Gutsy Gibbon) as part of its Dell Consumer Linux lineup along with the ability to legally play DVDs.

It has been confirmed that Dell is developing a consumer PC line that will run multiple versions of Microsoft Windows and Linux software at the same time using virtualization platforms to perform the magic.

The latest panic in desktop-Linux-land was that Dell would no longer be selling Ubuntu pre-installed on laptops and netbooks. Alas, for those who love drama, it wasn't true. In fact, Dell is expanding its Ubuntu desktop offerings.

Initially, I was skeptical about Dell's decision to sell selected consumer PCs with Ubuntu Linux pre-installed.

But after a few days of testing, I'm a skeptic no more. And I'm not alone. Dell insiders tell me that the Ubuntu PCs, introduced in late May, are selling well -- though they decline to share exact sales figures with me.

Dell is spending advertising dollars to promote PCs with Ubuntu Linux preinstalled. The move has significant implications for the business world as well. Here’s why.

It would appear that Dell is making life difficult for UK customers who want to buy a Dell PC running Linux.

Ever since Dell announced that they would be selling computers with Ubuntu pre-installed, I have wanted to buy one. This is not because I was unable to install Ubuntu myself, but because I wanted to reward Dell for choosing Ubuntu. I also wanted to make a statement that there was consumer demand for Linux to be pre-installed on computers.

Dell's U.S. website has started offering Ubuntu 9.04 on a Mini 10V and Inspiron 15N laptop. The move comes less than two months before Microsoft's Windows 7 launch - essentially reinforcing Dell's commitment to Ubuntu. But will Dell pre-load Ubuntu 9.04 on a desktop PC? Here's some analysis.
