HP Envy 23 vs Apple iMac 27 vs Acer Aspire 7600U :Best performer is.............

HP Envy 23                                                                                                                                               A lower-end version of the Envy 23 would make a decent, if unremarkable touch-screen all-in-one.

But, This high-end review configuration has no distinguishing characteristics, leaving it outmatched next to its competition in this price range.

The bottom line: A bland effort, the HP Envy 23 has nothing to recommend it over other Windows 8 touch-screen all-in-ones.

Apple iMac 27-inch                                                                                                                                      A thin new design and a competitive, logical set of core component updates keep the top-end Apple iMac on elite ground.

But, The lack of HDMI input is frustrating, and Apple's continued reluctance to add a touch screen may bother some.

The bottom line: Apple sticks to the fundamentals with the new iMac, relying on design, strong features, and overall polish to maintain its leadership among high-end all-in-ones.

Acer Aspire 7600U                                                                                                                                   Acer's new attention to look-and-feel shows in the Aspire 7600's clean appearance and responsive touch input.

But, The Aspire misses on price vs. performance, and Dell's 2,560x1,440-pixel resolution XPS One 27 makes 1,920x1,080-pixel screens like this one feel pedestrian.

The bottom line: Subpar computing components and a dominant high-end all-in-one from Dell hurt Acer's high-end, visually compelling Aspire 7600U.
