Potato Chips and Lap Tops...Technology at it's best...

I have sat here, unemployed, and noticed a few things going on... it's like fashion where the old comes back to be new... I digress, let me explain... In the 90's someone invented a tablet PC, and it was about $400 dollars more expensive then it's normal counterparts and why? Because you could flip the screen and write on it like a notebook...hoping it would catch on to college students they produced alot of these....alas due to price nothing ever came of it.... Then the Palm came around and people could carry their notebook in their pocket cept that the stylus sucked and half the things your wrote came out wrong.... Now they have these "Mini" PC's which are also tablets like the HP Touch Smart, which are revitilizing the laptop industry... wouldn't it have made sence to try this technology at a reduced price like now then? Perhaps the market would be larger already..... It's kind of like potato chips... Now they count the number of chips in the package (100 pringles?) where was this technology when I was buying half a bag of Lays?
