This suggests it has not been doing well

As $800(US) for a unsubsidised unit it's hardly cheap and I guess that's reflected in the sales figures.

Perhaps wait for a bit and if the sales remain low, perhaps Motorola will drop the price and then we can jump in. I like the Xoom and would get one over an iPad if I were to get a tablet at all.
