I'm using various versions of BD - 2008/2010/2011 all but one on machines running XP (pro & home) It's fair to say that I'm convinced of two things. 1: XP is by far the best operating system from MS so far. 2. BD AV 2008 is by far the best programme offered by BD so far.
I have a strong dislike of programmes that are overly large and take up space and resources and therefore are much slower - i.e Win 7 and 2010 and 2011 versions of BD. Worse of all the update time on the newer versions of BD is far slower than on 2008.
Why do newer programmes not get smaller and faster instead of bigger and slower ?
