Aside from Acer, we’ve heard that Dell is planning to enter the mobile phone biz as well. However, unlike Acer, Dell has yet to come out with their pioneering model, and based on this latest report, things aren’t exactly going Dell’s way.

According to Barron’s, Dell has actually unveiled both a Windows Mobile and Android based device to certain mobile carriers, but failed to get their approval citing the “lack of differentiation” for them to offer it as part of their line-up. We’re not exactly sure what Dell’s prototype actually lacked, but based on the chosen wording, it basically lacked any distinguishing feature to muster up even an ounce of interest from any of the participating carriers.

So it’s back to the drawing board for Dell, but they’re not at all discouraged with the snubbing that they recently got from carriers. In fact, rumor has it that they’re actually considering on buying out a struggling handset maker in order to help them get their first model out of the gates.

Well, all we can say is good luck Dell. Hopefully, you can get your first handset out before the year ends because with so many great offerings already slated to be unveiled this year, we’re pretty sure the competition will even be more intense come 2010.
