The result of these comparisons is a series of situational recommendations. Want a large-screen Windows all-in-one for passive media consumption? Get the HP. Want a big screen as well as strong CPU performance and some basic gaming capability? Then the Asus makes sense. Don't care so much about the screen size, but still want speed? I'll point you to the Lenovo.
Other than that, these three all-in-ones are remarkably similar. Asus offers most of what you'll find on the other two in terms of connectivity. You get an HDMI input, USB 3.0 and 2.0 ports, and an SD card slot. You also get some unexpected extras, like a VGA input to let you use the monitor as a display for older laptops, and eSATA for appropriately equipped external storage devices. The volume and video signal-swapping buttons on the display are also convenient.
Asus backs the ET2700I with a yearlong parts-and-labor warranty, as well as 24-7 phone support. It also seems to have streamlined its Web site to add at least the basics of online support. You can find chat, RMA information, driver downloads, and other help all on a single support page.
The Asus ET2700I is an appropriately expensive all-in-one given its fast components and 27-inch display. It would make an excellent system in a bedroom, dorm room, or other small setting where it can be used for both productivity and entertainment. Don't expect much from its audio output, and more committed PC gamers will want to look to the Lenovo IdeaCentre B520 instead, but for more forgiving games and even some light-duty multimedia-editing functions, the Asus ET2700I will serve admirably.Find out more about how we test desktop systems.
