Cambrey: Portable devices will take over.
Mr.Mumbles: Pfft. People have been saying that for a decade already... and mobile gaming has proven to be little else than being dominated by time-wasters and throwaway games. It's for distracted gaming and not much more.
no doubt mobile devices can have a nice place in our everyday life. Tablets are great for reading or watching videos, basic browsing on the internet too. But outside of (as you say) cheap time-wasting throwaway games, mobile devices rather suck.
I highly doubt i'll get hired to thumb-type 10 words a minute, when i can type 110 WPM on a normal keyboard. It's terrible for programming, writing anything of any real length, and screen sizes of mobile devices suck. I like using a BIG SCREEN and a controller, not clutching my phone/tablet and touching things on the screen or swiping to feed the little froggy at the bottom of the screen.
Maybe touch screen is sufficient, for say monopoly, or checkers, or chess. But trying to play RTS or something of real relevance will be terrible, not to mention squinting at the screen.
Then there's precision of touch. The touch on screens is VERY imprecise, which means they have to make HUGE buttons for you to touch that way you don't touch things you aren't suppose to.
Price-wise i find i'd rather get a laptop/chromebook than a tablet, I can get a chromebook refurbished for about $50, less than a tablet.
