my smartphone is a galaxy note 2 and i gave my ipad 2 away since i rarely used it so i dont have any apple bias but ....
The reasons everyone including stardock is going iOS first or iOS exclusive are
1. androids huge market share mostly comes from developing countries. while the 80-20 may be true world-wide ... in first world countries its more like just 60-40 and in the US even 50-50. and most of these millions of asians couldnt give a crap about western games just like americans & europeans rarely play the type of games popular in china,korea, etc.
2. its alot easier to make a game that works on ipad & iphone than a game that works on the hundreds if not thousands of different android devices.
3. multiple studies have shown that iOS gamers are more likely to buy stuff than android gamers.
I used to be annoyed about that too but when you actually play all these iOS exclusives you ll realize you wont miss out on much. If you want something casual to waste time android may have only 9971 games that provide that instead of the 10000 on iOS.
and if you want any game with some actual depth iOS has the same near zero that android has. Hunters 2, Warhammer Quest, etc. etc. ... i always wished them to be android until i played them and found out i m not missing out on anything. they are all not even a pale shadow of comparable PC games. i guess the x-com port is the single interesting iOS exclusive (well for me of course) but if you already played the hell out of that on PC there s no point in getting it since the replay value isnt that high.
the best "serious" gaming tablet is one running windows (well not RT of course). even if they lack the power for modern games you could at least play less demanding games like Panzer Corps (this is one might be comming to ipad but without all the mods & user made scenarios its 1/10 the fun.... ) or oldies like AoW2 .
edit: maybe i should add that i am talking about strategy and rpg titles ... the genres where i cant find any depth in iOS. its entirely possible that there s trading card games etc. with tons of depth on iOS/Android - i wouldnt know as those arent genres i m interested in.
