Excerpt: All-in-one desktops occupy a very unique niche. In the simplest sense, they are a compact desktop computer, with all the individual peripherals integrated to create a single unifying design. There are advantages to this quality alone. The AIO's smaller footprint gives you more freedom to clutter your desk with other odds and ends. Having the guts of the computer contained within the same chassis as the monitor also minimizes cable clutter.
Conclusion: I measured the power draw of the TouchSmart 520 using a Kill A Watt power consumption meter. At Idle, the system fluctuated between 60-65 watts. I used a combination of Prime 95 and OCCT’s PSU stress tool to generate a full load on the system of 132 watts. The system remained virtually silent throughout stress testing. I had high hopes for the Beats Audio on this system given the ample space for sizable speakers and HP didn’t disappoint.
Excerpt: All-in-one computers aren’t often looked upon fondly by geeks, but they’re a segment of traditional desktop computers that’s gaining attention while old-fashioned towers fall out of the spotlight. The reasons for this are not hard to understand. All-in-one PCs are far more attractive and also easier to manage. Most of them ask that you do nothing more than plug in the power and go. You can connect to your peripherals and the Internet via Wi-Fi.
Conclusion: Unless you plan on doing a lot of processor-stressing heavy lifting, such as HD video editing, one of these more modest configurations could be a better fit. Pair that under-$1,000 price with the TouchSmart's big, crisp touch screen and improved design, and we're willing to bet it will lure away more than a few potential iMac buyers.
Pros: Design is both good-looking and highly functional, Substantive touch software, Excellent application performance, Impressive audio and video output
Cons: Radeon graphics in test model didn’t add much gaming muscle, Windows 8 would make this machine more appealing, but won't be available for months
A 23in touchscreen PC that can be quite fun to use, especially in a family setting

Summary: The TouchSmart 520 is a capable computer system for everyday tasks, but its touchscreen offers a better way to interact with your content. Simply point to, drag or tap your files to let the magic happen. It's a very decent home machine that should go down well with kids especially, but we do wish it had a better graphics card.
Pros: Smooth 2-input touchscreen, All-in-one design, Full HD
Cons: Slow graphics performance, No digital audio out
Summary: HP has more experience with touchscreen all-in-ones than anyone else, and it shows. Its latest Touchsmart is a tidy package with an innovative hinged design that’s stable and easy to adjust, and the responsive screen picks up gestures quickly and smoothly.
