I left Windows behind when I purchased my Ubuntu PC. But some folks, naturally, want to run both Windows and Ubuntu. The following video shows one way to set up an Ubuntu/Windows dual boot system. The total video runs nearly 14 minutes.

Now here’s an interesting read. Microsoft and AMD are promoting a low cost $500 (US) PC in India, hoping to bring computing to the masses. But in India, low-cost PCs actually start around $300 (US), according to AP. Memo to AMD: Maybe you should remove Windows from the system and go with open source to hit that $300 target…

Wow. That was fast. Less than a month after Dell began selling Ubuntu on selected desktops and notebooks, the company has introduced more Ubuntu systems. Let’s think about that for a minute: Imagine if Dell introduced more Windows Vista systems four weeks after initial launch because customers were so excited? That didn’t happen. But it is happening with Ubuntu.

A few days ago, I mentioned that my biggest challenge with Ubuntu involved my son. The only reason he continues to use our Windows PC is because of iTunes support. So I asked readers for some suggestions: Are there ways to (A) make Ubuntu work well with iTunes and/or (B) make Ubuntu work well with an iPod. I got flooded with suggestions. Here are some of the most interesting ones.

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.

Well, quite a few folks flamed me for my “Four Reasons to Avoid Ubuntu” post. Some readers said my info was too basic. Others said the info should have more clearly focused on Ubuntu limitations rather than broader Linux limitations. I accept the criticisms. But I also want to point out: This blog was launched to help everyday PC users — millions of consumers who are frustrated with Windows — consider a move to Ubuntu.

There’s growing speculation on several forums that Hewlett-Packard Co. plans to launch PCs with Ubuntu pre-installed within the next few months or even the next few weeks. I need to get some sleep for some business travel on Tuesday June 26. But I’ll be sure to follow-up on this lead sometime late in the day. Stay tuned.

Sure, Dell is new to the Ubuntu PC market. But plenty of smaller PC suppliers have long supported Ubuntu. One prime example: ZaReason Inc., a PC maker made up of volunteers. I reached out to Cathy Malmrose, CEO of ZaReason, to get a feel for the company’s customer base and market position, and to get her views on Ubuntu’s longer-term prospects. Here’s a look at our conversation as it occurred over email.

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.

A few hours after setting up my new Dell Ubuntu PC, my wife jumped onto the system. You know her kind: She is an Apple Mac OS fan who uses Windows — but doesn’t really like Windows. So, how did she do with Linux?
