"It’s finally here. Later today, Dell will offer U.S customers three different systems with Ubuntu 7.04 installed: the XPS 410n and Dimension E520n desktops and the Inspiron E1505n notebook."

I’ve spent recent days praising Ubuntu’s simplicity. My $1,400 investment in a screaming Dell machine running Ubuntu was money well spent. But I also realize Ubuntu won’t appeal to all users. In fact, I can think of at least four key reasons why many Mac and Windows users won’t want an Ubuntu PC. Here they are.

Plenty of folks are confused about Dell’s commitment to Ubuntu, the Linux distribution promoted by Canonical. In recent days, old rumors about Dell abandoning Ubuntu have returned. But in reality, Dell indicates it is preparing to ship systems with Ubuntu 10.04.

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.

Dell’s Inspiron Mini 9 Netbooks running Windows XP and Ubuntu are on sale. But US newspaper advertisements from Dell and Best Buy show Dell’s Windows XP netbooks to be a far better bargain than Dell netbooks with Ubuntu Linux. Here are the details.

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

Even as Dell prepares to ship computers with Ubuntu 10.04 pre-loaded, the PC giant is battling rumors that it no longer remains committed to Canonical's Linux distribution. For Dell, it's time for a clear, concise statement that specifically describes the company's history with Ubuntu and next moves with the operating system. Here's why.

Dell is getting ready to launch systems with Ubuntu Linux, but is not yet releasing details of the final specifications. However, the company did say on Friday that as well as a consumer version of Ubuntu, it had plans to launch a small-business version "in the future".
