| 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. | Updated with a touch screen, a new stand, and up-to-date components, the Dell XPS One 27 leads the inaugural class of
Windows 8 PCs. | 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. | HP has made an aggressive move in the budget PC space with this big-screen all-in-one that will serve as an affordable, generally capable home computer. |
