It's one thing to do digital photography through a laptop or desktop computer where the games are actually decent and you can play for three hours after you do your photo session, but the crappy games they have on the Google Play for tablet computers just isn't worth it to do anything else but look at websites and play crappy Bejeweled Blitz clones and cheesy looking slot machines.
Sure, there are arcade and console emulators that you can download on Google Play for the tablets but you can't properly control most of these games unless you're using an external gamepad hooked up to a USB cable. Even though digital photography is a cheap knock-off of traditional film photography, everybody seems to like it even thought they know that the invention of photography preceded the invention of the personal computer.
Racing games are a nightmare to play on the tablet computer, some shooting games don't work because you need two controllers to calibrate the game while some newer action and fighting games slow down to a crawl on an Android tablet computer. I believe that when it comes to gaming, the console systems and personal computers are here to stay.
