Its just like the ipad was when first out. It takes time for the apps to be made. You can run old Android apps on it too like the ipad.
Yes, it takes time, and it was months before the iPad got a lot of great, tablet specific apps. Now, they are endless. Fortunately for Apple, there was no other competitor in this market offering anything better. But the iPad has beem out for a year now when the Xoom and other tablets begin to trickle out.
As a buyer, your choice, right now, is between a Xoom that does pretty much nothing except run Honeycomb (which is, for many, apparently enough), and an iPad with basically identical or better specs (we'll see how Xooms battery is) and thousands of apps - including several excellent first party apps between iMovie, Garageband, Pages, and Keynote, etc. Not to mention all of the games, art and design apps, news and RSS feed apps, and many many other music apps. The options are literally endless such that anyone who buys an iPad can probably find over a dozen apps that really work for them.
And since Apple is leading by such a large margin, all the Xoom is going to get for the foreseeable future is ports of iPad apps that some of us have been enjoying for months now. And beyong that, developers will always release software into Apple's appstore before or alongside the Android version.
None of this is to say the Xoom is a bad device. Just that it is behind. And all the people bitching and whining about the iPad and claiming the Xoom is so obviously a much better device because it has widgets or some **** don't know what the hell they're talking about.
