If you want to hear me, I have tried the Surface RT (350$)
Samsung tablet and iPad.
From all these three, they had essentially quad cores and dual cores.
If you want to waste your money, go for any of these three.
I couldn't believe that so many people went with this stuff, when there were Chinese tablets for only 60$-70$ (mine is 70$)
I bought myself a Chinese tablet a year ago and still working perfectly.
Opens PDF, plays latest games (the only game I could play on low was GTA III) and it really depends what tablet you get. Mine has 512 DDR3 of ram and Mali 400 as a GPU. 1.2Ghz processor, which opens everything possible.
These are somewhat the specs of Samsung Galaxy SII and we are talking about a tablet cpu here, not phone cpu!
So it will be much more worthy to spend money on any of these Chinese tablets.
Btw, it has webcam, it has office stuff and everything a tablet can do. Even SD card place for 32GB. My friends were so unhappy when they saw me with 2 tablets at hand for 1/3 the price of their tablets 🙂
I was playing Final Fantasy III 2 days ago and it was super!
(I even have Photoshop mobile version which opens perfectly and there is even autocad!!!)
Also mine are 7" version, but you can get 10". Also the cpu and gpu must have changed and become even better I guess.
