Toshiba LX835-D3380 vs Samsung Series 7 All-in-one vs Sony Vaio Tap 20:Who is the best?

W.A.Khan,                                                                                                                                                 Toshiba LX835-D3380                                                                                                                             A fast CPU helps distinguish the Toshiba LX835-D3380 from its Windows 8 all-in-one competitors.
But, Toshiba played it safe with this system, offering few interesting features to go with the new operating system.
The bottom line: Look no further than the Toshiba LX835-D3380 if you want a comfortable, speedy all-in-one on which to learn Windows 8.

But, Samsung sacrificed performance to keep the price down, and a gesture recognition feature is best left ignored.
The bottom line: The Samsung Series 7 isn't the fastest, or the most fully featured midrange all-in-one, but casual PC users should consider it for its affordability and overall polish.

But, The touch screen has some frustrating drag, and Sony made a few missteps among some otherwise reasonable sacrifices for portability and price.
The bottom line: A compelling experiment in tablet-desktop hybridization, the Sony Vaio Tap 20 is a great fit for home tech enthusiasts willing to try something new.
