With apologies (to those still waiting), I'm really enjoying it so far.
I tried watching BBC iPlayer and, for the first time, it is actually watchable, no stuttering, no freezing. And in HD, of course.
I have also worked out that I can amend my overnight backup script to upload at least some stuff to cloud (details to be decided) thus reducing dependency on optical discs stored in the garage. With all the photos I care about, plus all my source code, plus letters and other documents and all email since the dawn of home computing, it comes to a bit under 20GBytes. I reckon that'll take a bit over four hours. That is a lot, but will be complete by breakfast time. Whereas before, it would be about 4 days or more.
