HP has introduced a pair of convertible tablets with detachable keyboard docks. The most interesting of the two is the SlateBook x2, which combines a 10.1" display with Nvidia's Tegra 4 SoC. I believe this is the first Tegra 4 tablet that's been announced, and HP hasn't pulled any punches. The display has an IPS panel with a 1920x1200 resolution, there's up to 64GB of solid-state storage onboard, and Android 4.2 serves as the OS.
Like Asus' Transformer tablets, the SlateBook's dock contains an auxiliary battery. It also boasts a "full-size" keyboard and a clickpad with multi-touch gesture support. When docked, the keyboard and tablet measure 0.8" thick and weigh 3.1 lbs. HP's site doesn't provide dimensions for the tablet component alone, though. There are no battery life estimates, either.
At least we know how much the SlateBook x2 will cost. The tablet and dock will be sold together for $480 when they become available in August. That seems reasonable given the hardware involved, especially since Android shouldn't consume too much of the internal storage. If you need extra gigabytes, the SlateBook also has a USB 2.0 port and an SD card slot.
Android not your style? You could go with the existing 11.6" Envy x2, which is based on a Clover Trail Atom CPU. Or you could wait for the August arrival of the Split x2, which will be available with more powerful Ivy-based Core i3 and i5 processors.
The Split x2 has a 13.3" IPS panel with a painfully pedestrian 1366x768 display resolution. At least the storage config is interesting, though. HP's site says the machine can be configured with up to 128GB of solid-state storage and a 500GB mechanical hard drive. I wonder if those devices are split between the tablet and dock portions of the system. Hmm.
Including the dock, the Split x2 weighs 4.1 lbs and is 0.9" thick. The dock houses a secondary battery, but again, there's no word on run times. We do know the starting price: $800, which presumably applies to a Core i3 config with a smaller SSD.
With Haswell convertibles expected toward the end of the year, it's hard to get excited about the Ivy-based Split x2. The relatively low screen resolution certainly doesn't help; I don't understand why HP opted for such an uninspired display. Of the three x2 convertibles in the PC maker's lineup, only the SlateBook ventures beyond 1366x768—and it's the cheapest of the three by far.
