it is pretty poor form to have every theme cost money, surely that was a selling point of ahome, that it gave you easy access to themes, only then you find out, you have to pay for each one! Well, I bought ahome, but I definately wont be buying any themes, ahome added functionality as well as aesthetics to my phone, the themes are just about aethetics, I can wait until google makes it easier for users to change themes on their phones and free ones start rolling in. In the same way that all of the extra functionality that ahome gives, will soon enough, be provided by google (e.g. ability to add extra screens to the three base ones, ability to add more widgets, autorotate).
I really don't see Google holding our hands with everything. (adding screens, widgets, themes)
That is why we have the market. You can always root your phone to get custom themes. Changes background, icons, notification bar (instead of it being gray), transparent notification pull down bar, and more!
