ACER ICONIA W500 is really good and has Windows 7. It is upgradable to WIN 8 and believe it works wonder in WIN8. It is a mini computer with touch facility. This TAB is good and friendly.
Cons:
1) Screen is bright - LCD with HD
2) Touch response is impressive that too with Windows 7
3) I believe it works well with Windows 8
4) You can go ahead installing any software since the Windows OS
5) Value for Money
6) 2GB RAM with 32 Internal Storage and also expandable with SSD for more storage
7) Internet with Wifi and Ethernet are good - gets connected quite quick
Pros:
1) When you use it as TAB, both USB ports are blocked at the bottom. It would have been nicer if it is the other two sides. It would have been very useful for many purpose
2) Battery back up is not as expected
3) In built 3G would have been PLUS instead optional
4) Internal Storage is only 32GB but upgradable
5) When keyboard is docked with TAB, You cannot fold and close it like other Laptops.
Overall, I am proud user of ACER ICONIA W500. Worth for money.
I am quite unhappy for the USB ports are placed at the wrong place.
