Wired's Gadget Lab, hardly an Apple centric site went looking for Android tablet optimized apps for your Xoom... here is their March 30th report:
Thanks for all the FUD, but the point is that “tablet-optimized” is itself a loaded term. As Android developers have been dealing with varied screen sizes in their apps for years, the vast majority of apps originally written for phones scale perfectly well to the Xoom’s screen size. Hence why I say these people have clearly never used one before. Just because apps originally written for tiny iPhone screens (remember, the iPad came out before the iPhone 4, which introduced better resolution) looked like crap on the much larger iPad screen doesn’t mean Android apps do.
Take for instance SlingPlayer. It’s not “tablet-optimized”, but it looks great on the Xoom. Why? Because the people who wrote it were smart enough to code their program to adjust for resolution. They’re not the only ones - every single program I use on my phone (Droid X) also works on my Xoom, with no noticeable drop in quality.
