None of this actually looks at all that great personally. I think you've missed out some important factors.
1. Growth of Android is centred around the cheaper devices. Apple completely dominates the high end market for phones. That means Android 2.3 adoption won't be that big in 2011. Furthermore huge sites like Amazon are getting into the market too so theres no assurance there and Amazon is device agnostic and they are only just behind Apple in digital distribution, Sony is nothing by comparison.
2. See above.
3. For a supposedly entry level product I suspect it'll be very expensive and niche. Since it only supports PSP1 its going to be a lame duck as a game device.
4. Android apps work on analogue sticks? Google TV maybe, Android apps no.
5. Sony has never really gotten the synergies to work between devices, why are they suddenly going to get that right now?
2011 and 2012 android 2.3 _will_ see wider adoption. 1.5, 1.6, and 2.1 devices are nearing their end of contract. Those people are going to want 2.3 at the very least.
1) The Amazon store and Playstation Suite are just Store Apps. They will be able to sit beside the basic Market Store as well as eachother. If you want the full android experience with all the apps you will need all of these stores.
2) See above.
3) Very expensive? On contract it will probably be no more expensive than the last phone you bought, unless you got a crap phone. It will play ps1 games, psp1 games, minis, movies, etc.
4) Playstation Suite games will work on analogue sticks. Normal android apps will not be downloadable onto the PS3. Just because android might be on the PS3, doesn't mean it will have support for default android market place.
5) They've done no worse than nintendo in this area, and in fact have done just fine imo. I can play PS1 classics on my ps3 and PSP right now, which I do all the time. Once they get a cloud service up where save games can seamlessly transfer from the two devices I can just go from one to the other in minutes. Remote play works. ETC.
