Where did you get these numbers? In my research, I couldn't find good comparisons at all. I saw some info in various places attributed to Canalys that showed 33 million iOS vs 32.7 Android unit sales in Q4. I also saw Schmidt claim 300k daily Android phone activations in Q4 with Apple's Q4 earnings report extrapolating to 375k daily iOS sales. Did Android have 75k daily sales of non-phone Android devices? Maybe if we include Nooks and things? Is this even really a useful comparison between two things anymore? Would a consumer recognize a Nook as being the same thing as a Droid, in the same way they recognize an iPod Touch is the same thing as an iPhone? This isn't an idle question since, e.g., millions of the Android activations are coming from phones in China with totally different user experiences. In my opinion, Android is not homogeneous enough to compare against iOS in the way that Windows vs Mac OS used to be.
Those Apple figures are for calendar Q3, Apple's financial Q4 so you're not comparing the same time period. Apple generally get a big bump in iPad and iPod sales in the christmas quarter.
I'm fairly confident that Android is far enough ahead in smartphones sales (i.e. more than double globally, more than triple in the U.S.) that you can include iPods and they're still ahead and the gap is growing. I'll wait till I see a few quarters of numbers for the Android tablets before I'd be happy assessing how they're doing against iPad sales.
edit: Here's what Apple call their Q1 results, covering Q4 2010:
iPod sales declined 7% year-on-year, the 33 million iOS (pod+pad+phone) number mentioned above which would roughly equal Android smartphone sales last quarter works out if you assume half of all iPods are iPod Touches (I have no idea if that is true, either historically or currently).
Ophone (the China Mobile Android fork) sales were about 1/3 million last year, which is less than half a percent of the 70 million Android sales in 2010. They were only aiming for 1 million so even if they hit that target it wouldn't make much difference. Android sales generally are growing fast while Ophone is supposedly a failure because it can't keep up with mainline Android development.
The Canalys numbers only covered smartphones (16.2 for Apple in Q4 2010) so the rest of the figures must have been added by someone else.
And the Schmidt number was over 300,000 daily activations at the start of Q4 (it had jumped around 100,000 in the previous two months and growth appeared to be accelerating). Canalys numbers translate to about 366K per day averaged over Q4. It appears later sales rates must be over 400K to bring that average up to that level.
