In the US Dell has famously started offering Ubuntu on selected machines as a direct alternative to XP or Vista. Fortunately these machines cost less than their Windows counterparts and that's good, but Dell really should consider moving beyond offering Ubuntu; and here's why.

In cases where computers are available pre-installed with either Linux or Windows, it is almost always the case that either (a) the Linux one is slightly less expensive or (b) the Windows one is actually less expensive, so you might as well just buy the Windows version and install Linux. Apparently, this is not always the case.

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.

It would appear that Dell is making life difficult for UK customers who want to buy a Dell PC running Linux. Being a snooping journalist myself, I went to have a look for myself and indeed it is a lot harder to buy a Linux powered Dell than all the hype, fuelled in no small part by the Dell PR machine of course, would lead you to believe.

For roughly two years, readers have told WorksWithU they have a difficult time finding Ubuntu desktop and laptop options on Dell’s U.S. Website. Apparently, Dell heard the constructive criticism. Only a few weeks after Windows 7's launch, Dell is giving Ubuntu more real estate on the Dell U.S. website. Here's the scoop.

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.

There have been many whispers and flat out rants in the blogosphere about Dell’s lack of advertising, support and passion for the Ubuntu systems that they are selling. This could actually hurt the Dell initiative.

Finally the OS juggling games can stop and we can just have Ubuntu and Windows options on all of Dell's computers from now on. Well, all of their netbooks, that is. One of the most annoying things about Dell is their seemingly random decisions about what computers are going to be offered with what OS. Apparently, though, Dell realized how annoying this was.

Dell has shipped close to 40,000 systems pre-installed with the Ubuntu flavor of Linux, according to multiple sources. By most accounts, that's a heck of a total for what remains more or less a fringe operating system.
