HP is also including more features in the Split X2's keyboard dock to make the hybrid worthwhile to buy as a package. It has up to 128GB solid-state drive storage, and the keyboard base offers an additional 500GB of hard drive storage.
The Split X2 runs on third-generation Intel Core processors code-named Ivy Bridge. HP did not say when Intel's fourth-generation Core processors will be in Split X2. Intel will announce the new processors, code-named Haswell, in June.
The new hybrids are part of the X2 product line, including Envy X2, which also comes with a keyboard dock and a detachable screen.
Many users are looking to upgrade PCs and are also interested in hybrids, Conrad said.
"We see enough interest in it. The response we got to Envy X2 has been pretty positive, all things considered. It's been positive enough where we can expand the lineup," Conrad said.
Tablets are hot, but adding a keyboard and selling it in a PC-like package may not go down well with customers, said David Daoud, research director at IDC.
"I find the strategy risky because why would customers need to be forced to acquire a separate keyboard if it is not physically attached," Daoud said.
IDC is making conservative projections on hybrid shipments as there is no established market yet for these products, Daoud said. PC makers are trying out new designs to see what sticks.
"You're bound to see a lot of products, but many are not likely going to make it," Daoud said.
HP also doesn't have the brand-name recognition of a company like Apple. But buyers would be willing to pay a premium for a MacBook Air with a detachable screen.
"Think of a super-thin laptop like a MacBook [Air] that's also an iPad, people will buy it," Daoud said.
