The launch of Windows 8 has led to the birth of a new computer category: the tabletop PC. Whether the idea of using what's essentially a 20-inch touchscreen tablet on a flat surface will be successful is still very much to be determined, but HP is joining Sony and Lenovo in the nascent market with the new Envy Rove 20.
The Envy Rove is notable compared to the Sony Tap 20 and Lenovo Horizon for its support of Intel's Haswell processors (which could be added to those other systems, but they currently use Intel Ivy Bridge CPUs). It provides a 1,600x900 IPS display for users to tap and swipe on, along with built-in Beats Audio technology to provide superior sound. It also includes a stand so it can function as a "normal" all-in-one PC, which might come in handy sometimes because the Rove 20 weighs roughly 12 pounds.
According to Engadget, the Rove 20 will include a 1TB hard drive and 8GB of solid-state storage when it ships in July. Unfortunately, HP hasn't yet provided an official price, though it's supposedly under $1,000.
If you don't need to schlep something like the Envy Rove 20 around the house, you might prefer one of the two new Pavilion TouchSmart all-in-ones HP has also announced. There's a choice of a 20-inch model or a 23-inch flavor, the latter of which sports full 1080p HD resolution. Both offer touchscreens, though they are arguably trickier to use than if they could lay flat like the Rove 20, and will come with your choice of AMD or Intel Haswell processor.
The Pavilion 23 TouchSmart will be available on June 5 starting at $749.99, whereas the Pavilion 20 TouchSmart will start being available from June 26, but cost only $619.99 for the base configuration.
