NEW YORK, N.Y. - A research firm says Microsoft is seeing slow sales of a version of Windows designed for thin and light tablets, even as the tablet market as a whole is growing.
Researchers at IDC say manufacturers shipped 200,000 tablets running Windows RT, the special version of Windows for iPad-style tablets, in the January to March period. That's down from about 900,000 shipped in the fourth quarter.
Microsoft launched Windows RT in October, along with the Surface tablet. The software runs on a few tablets from other manufacturers as well.
Microsoft's larger Surface Pro tablets, which run standard Windows 8, did better. IDC didn't specify how many, but it's at least 700,000 based on the figures provided.
Meanwhile, the global tablet market more than doubled to 49.2 million units.
