There are many things you can change about a tablet, except for its diagonal size… or can you? The Intel Haswell prototype that was shown at CeBIT last month is notebook/tablet hybrid, that has an adjustable screen.
It can go from 13 a inch Full HD display to a 11.6 inch screen whenever it’s detached from the keyboard base. If you’re wondering how that is possible, well, the display introduces letterboxes by adding a virtual bezel to expand the basic one. The touch input is disabled in the expanded area, in order to keep in line the feel of the device.
The prototype sounds interesting, but I guess that the final version may be a bit too expensive for the mass public. For those of you wondering, the real world performance benchmarks in existing code show a 7 to 12% clock for clock improvement for Haswell compared to Ivy Bridge.
