HP is hoping to build on what it sees as an area of growth in the desktop market for all-in-one systems and touch-screen devices with new models in the Omni and TouchSmart ranges for consumers and enterprises.
The low-end Omni 120 will sport a 20in display, along with a 750GB hard drive and Intel or AMD processors and graphics chipsets. The 21.5in Omni 220, meanwhile, will feature a more powerful quad-core Intel processor and optional Beats Audio hardware.
Randall Martin, HP chief desktop design strategist, told reporters that the systems are designed to be transported easily between rooms and locations.
"We realise folks are moving these around all the time. With only one cable to hook up, it is a really compelling use scenario," he said.
HP is also updating its TouchSmart line for home and business users. The systems will better integrate the TouchSmart interface with the standard Windows operating system, and will feature touch-optimised applications such as Twitter and Facebook clients.
The company is pitching the TouchSmart Elite 7320 at enterprises for applications such as customer service or support. The 21.5in system will support Intel processors up to the i7 line and up to 2TB of storage and 8GB of memory.
The system will also feature a new stand that allows the screen to be tilted up to 30 degrees.
Marc Spier, director of consumer desktop marketing for HP's Personal Systems Group, explained that the company has found itself with an interesting marketing problem as all-in-one and touch-screen designs become lighter and thinner.
"We need something that is clearly not a display. We need to make sure that, when customers pass it on the shelf, they see it is not just a display," he told reporters.
HP hopes to make the Omni and TouchSmart systems available in September.
