Doing some extrapolation, Deutsche Bank figures that XOOM sales are around 100,000 so far.
The math isn't hard. Look at Android Dev's latest numbers for Android sales (April 1st)...
Duetsche Bank figures that .2% of Android devices that accessed the Android Market translates to 100,000 units. This means that they estimate 50 million Android devices accessed the Android Market over the last two weeks. Considering Android's run rate is about 10 million devices/month after a steep climb, that seems reasonable (though Google(goog) doesn't publish such numbers).
There one device shipping that runs Android 3.0 (though developers have ported to a few other machines) is the Motorola (mmi) XOOM.
The XOOM came without Adobe's (adbe) Flash, without the ability to use its own SD card slot, and only a few apps that took advantage of its larger display. It also runs a very new, largely untested version of Google's Android Honeycomb.<!-- more -->
Considering this, 100,000 units isn't horrible – that is, unless you look across the isle at Apple's (aapl) iPad 2 which also doesn't have any official numbers attached to it, but probably sold 100,000 units before lunch on day one of sales. Many experts think that millions if not tens of millions of iPad 2 have been sold already.
It is important to remember that the first Android phone, the G1, wasn't a critical success for the first year of its existence. Google kept iterating however and wound up with significant success with the Droid about a year later. With about 50 new tablets coming down the pipe running Honeycomb, it is still way too early to count Google out.
As for the XOOM, it didn't even beat the older Samsung Galaxy Tab in PC World tests.
It will be interesting to see how the landscape changes over the next year.
