The performance gap between the HP and the Lenovo is persistent across our benchmark tests. In clock speed, as well as in available processing threads, the HP's 2.8GHz, four-core/eight-thread Core i7 chip is faster than the Lenovo's 2.5GHz four-core/four-thread Core i5 2500S. The disparity isn't huge, and the Lenovo's extra RAM helps it stay competitive, but if you demand top speed, your best bet is the HP.
One criticism I have for both PCs is the absence of an HDMI input. Lenovo does offer a TV tuner, but that's a poor substitute for an HDMI-in, which can turn your all-in-one into a second display for use with any modern video source component. The Lenovo is even primed for this feature; you can see the spot for the unused port on the back of the system, and it offers a button to swap the video input on the right side of the chassis. HP at least offers the possibility of adding an HDMI input via a $50 upgrade, but that should be a standard feature for every all-in-one out there, since it's cheap and offers a dramatic increase in system utility.
The inputs you do get with the Lenovo also feel spare. You get six USB 2.0 jacks, an Ethernet input, an old PS/2 keyboard port, an SD Card slot, and a pair of analog audio jacks. USB 3.0, standalone video output, and digital audio are all absent, making this system a disappointment in terms of its connectivity.
Lenovo's service and support policies hold to the near-universal industry standard of one year of parts and labor accompanied by a 24-7 toll-free tech support number. You can add at-home service and extended warranty coverage if you purchase your system online from Lenovo directly. You will find basic drivers and documentation on Lenovo's support site, but we wish the site gave you more direct access to the product-specific information.
Comparing midrange all-in-ones depends heavily on pricing, and finding a stable figure for a given product these days can be near impossible with the preponderance of short-term promotions and retailer-specific discounts. As long as the spread remains consistent between the HP Omni 220 and the Lenovo IdeaCenter B320, the HP system is faster, has a larger display, and has better overall features. The only exception comes with the Lenovo's 2TB hard drive. If storage volume is your top priority, the IdeaCentre B320 is worth a look.
