  Yup.  Same processor as used in the Commodore 128, too.

  I have one.  I like it, but my 48SX is still my main calculator at my
desk, and an 41CV is my main calculator on the bench.  I don't do much
complex stuff (no pun intended) on the 35S, so I haven't hit any of the
reported bugs.  I received it as a Christmas gift the year it came out.
(which actually did make me very happy)
