Apple iMac 21.5-inch vs Asus Transformer AIO vs Samsung Series 7 All-in-one ;Which is your Choice?

W.A.Khan,                                                                                                                                                  31/3/2013,                                                                                                                                                                                                Apple iMac 21.5-inch (November 2012)                                                                                                                                         Apple's attention to detail extends to the 21.5-inch version of its thin-looking Apple iMac.
But, Windows-based all-in-one PCs offer tough hardware competition in the sub-$1,400 price range.
The bottom line: The 21.5-inch iMac will be a compelling lower-cost all-in-one for Mac loyalists, but you can get more capabilities from similarly priced Windows all-in-ones.

But, Remote desktop technology makes using Windows 8 in tablet mode unreliable, and you might prefer to wait to buy until later this year when the category has matured.
The bottom line: You'd be smart to wait and see how the market develops, but Asus has used the freedom of the still-forming all-in-one/tablet hybrid category to create a compelling Windows 8/Android device in the Transformer AIO.

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.
