I don't know where to start so I'll just sum it up:
-You don't need a laptop configuration but you can;
-Doing office on my smartphone is a disaster;
-Doing iWork office on an iPad is bliss;
-Screensize is big;
-Batterylife rocks on tablets;
-No stupid fan holes;
-It makes zero noise;
-There is no charger with thesize of a brig;
-You can keep that keyboard in your backpack and use the damn thing;
-iPad sales in 9months > all sales of all tablets ever;
-Everybody can learn to work on an iPad in a day Vs. figuring out how desktops work even after ten years.
So... you tell me why this is failing...
