If you want an all-in-one, space-saving, big-screen PC, HP's Omni 27 may be the best alternative to the 27-inch iMac, and has some features you won't find on the iMac, including a Blu-ray drive and a better sound system. It's also cheaper than the iMac, going for about $1,200 vs. $1,700 for the iMac. But it lacks a dedicated graphic card, something we think is critical for an entertainment PC. The iMac is a more powerful computer, provides more flexibility for expansion and, yes, runs Windows.
