Acer W510

it is a great tablet, it runs windows 8 out of the box, it has a good browser, has data encryption for security, can connect to other phones and devices, charge them,can also play Android applications via bluestacks
while android devices can't connect Windows or Mac ,it can do it all
finally a great value for money than HP envy x2.

Flipkart is flipkart, again got the delivery in given timing, product was very nicely and safely packed.

Taking about the product itself,
The tablet is very sleek, light compared to ipads, display looks very sharp, its an ips display so does have great viewing angles.
Tablet comes with 33gb free space, and 64gb sdxc cards can be installed, I am personally using 64gb full sdxc card and its working very well.
Camera is good not kind of those on smartphone, but even nobody expects that.
Overall...

Windows 8 runs perfectly fine all apps in windows store is compatible with it
