The current Windows desktop software is
supposed to work, but it didn't on my two XP PCs; the problem was the
lack of a PlayBook driver, which didn't come with the PlayBook, wasn't available at RIM's website, and wasn't available to Windows
Update.
The hardware is exceptional and the software is quick and responsive, although it does
lack some basic navigation features but Sony is
supposed to issue an
update in early 2018 with a number
of improvements.
