HP definitely isn't showing up to IFA empty-handed. To start, it's greatly expanding its line of detachable Windows tablets beyond the middle-of-the-road Split x2. The star of the show is undoubtedly a revival of the Envy x2 line. It's much more powerful this time around -- the tablet is using Intel's fast-yet-efficient Core M processor instead of an Atom chip, and it now comes with a much larger 13.3- or 15.6-inch screen. HP has also switched from a (relatively) conventional laptop design to a fabric-wrapped Bluetooth keyboard that's supposed to be more flexible. Be prepared to pay for all these upgrades, though. The 15.6-inch Envy will cost $950 when it reaches the US on November 5th, and its 13.3-inch counterpart hits October 29th for $1,050.
