The HP Spectre gets both hybrid and ultrabook editions
The HP Spectre comes in both detachable (hybrid) and ultrabook designs. Each device features an aluminum case, and according to HP the ultrabook version of the Spectre 13 is the first fanless detachable ultrabook with a Haswell processor. That's definitely a lot of qualifiers, so it's also probably true.
The laptops also include Beats Audio speakers, and each features a 1,920x1,080-pixel-resolution IPS screen.
In my demo time with the X2 -- HP had the ultrabook version at our meeting, but the prototype unit was not working at the time -- the tablet felt like a well-designed, surprisingly light high-quality device with a fairly thin slate and a large comfortable keyboard with tactile metal keys.
Each device features dual USB 2.0 ports and a full-size HDMI port and the ultrabook additionally includes a full-size SD card slot, mini DisplayPort however physically, the Ultrabook differs in one major way. It features an extra wide touch pad that allows users to use certain Windows 8.1 gestures without touching the screen. In other words you can use the touch pad to not only swipe, but bring up the charms menu as well.
The middle section of the touch pad feels like a normal touch pad, only noticeably wider than typical; however, as you slide your finger to the far left or right there's a tactile tell that indicates when you've entered the space that controls the Windows 8.1 charms menu. It's a good method to keep you from constantly bringing up unwanted options.
The Spectre 13 X2 starts at $1,099.99, while the Ultrabook version can be picked up at a starting price of $999.99.
There's no release date yet set for either Spectre 13, but HP says to look for them before the end of the year.
