Microsoft seems to have gotten the design and form factor right with its new Surface tablet computer. But the user interface, not so much. That's an odd conclusion to make about a device from a software company that usually lets others do the manufacturing.
Still, that's how I felt after feeling the heft of the device, examining it from all sides and making a few swipes at the screen. The Surface has a touch keyboard cover that feels great and, to me, is a big step forward for tablets. The tablet's software interface, however, seems non-intuitive and sluggish.
