and outdated + bad software from bad companys are not an argument for 32bit.
amd+intel are only duopolist monopole mafia companys and because of his the price is so high.
sorry SoCs is just a buzzword in the end it dosn't matter.
sure its cheaper (but in my point of view its the only argument)
"Lessened power requirements:
* less cooling needed.
* smaller battery for same battery life."
sure but you buy it for: no 64bit, less memory ram ,much slower
for me "Be slower with less features" is not a feature.
in the end the driver support wins the radeon driver for example do have a bad power management. But i don't think you have the man power to beat the radeon driver in features and power management.
but maybe you are the master of the universe ?
and if not only cheap a 64bit cpu+more than 4gb ram. and a openGL3.3 gpu
