Yes, it is really just a matter of time... and of Android tablet manufacturers finding the sweet spot between features and pricing (which ASUS has with the Transformer but other manufacturers have been iffy with thus far)... but that too is just another thing time is already sorting out.
There is no way Android represents 20% of the tablets sold this year. Seriously, I doubt it's 5%.
It's incredible that anyone can make that claim when it's patently obvious from simple observation that there are hardly any Android tablets in the wild. If they're going to pull numbers out of their ass to create the perception that Android is succeeding on tablets, they should at least make up numbers that are marginally plausible.
I'm not clear as to if you were trying for irony with that statement so I'll call you on it:
Seriously, I doubt it's 5%
...they should at least make up numbers that are marginally ...
If your going to mock someone for "making up" numbers try not to make up numbers of your own in the same post. The op provided data, you did not. Unless you were going for irony; in that case, well never mind.
I don't think it's incredible to make that claim at all. The iPad has been around for quite a bit longer so you would expect to see a lot more of them in the wild despite only outselling android tablets by approximately a 4 to one margin at the moment.
Despite this, I still routinely see android tablets in airports. I saw a galaxy tab 7" tonight (along with 3 people using ipads in first class). I've also seen a few galaxy tab 10.1s and a couple of HTC Flyers.
To be clear, I also wonder if the actual ratio is 4 to one. I just don't think the number is completely outside the realm of possibility.

Android-based Phones were slower to get that much market-share, and we all know how that turned out. It's really just a matter of time.
