Allegedly Samsung have sold 1 million Tabs within 2 months of putting it on sale. [0] This isn't as fast as the ipad, but it does demonstrate that there's a market for non-ipad tablets. One of the things thats quite important in this market is that Android 3 is meant to be rather tablet oriented, and I think that will address his concerns. There certainly are a lot of cheap, poor quality, android tablets on the market at the moment but if you look at the Android phone market it also went this way. Initially people thought it would be loads of cheap asian cloners and it turned out that the best selling android phones were actually the high quality devices.

Now I don't want to start some 'Android vs iOS' discussion, buy whatever product suits your taste - thats your choice, but I do think its a little bit hasty to write off tablets from other manufacturers at this moment in time. Perhaps I've misunderstood and he is only talking about the present - but it seems like the author thinks there will never be a serious competitor.
