It's official: Microsoft (MSFT 1.69%) is unveiling its next generation of Surface tablets on Sept. 23. The first-generation models didn't fare so well, resulting in a $900 million inventory charge for the company last quarter, in part because Microsoft priced the device too high.

The software giant appears to be dropping its controversial "RT" branding in favor of a more unified lineup, although the fundamental differences between the two Windows variants will remain -- which may just lead to a new level of confusion. The newest chips out of Intel (INTC 0.63%) also call into question whether Windows RT should still exist, since the chip giant is aggressively targeting lower price points as well as improved battery life.
