Quick review:
I received my upgrade kit today (for my TS07), which contains very good instructions and a compact flash card with the updated software. It's as simple as taking it out of the wall, removing 4 screws, pop the CF card in, and put everything back. The software is automatically detected during bootup, and it detected the existing settings, so this was truly plug and play, kudos to Elk for making this process so easy!
As for the software, it runs really good on the PC, but on the TS07 it seems to be just a little slower than the older version. Granted, I am extremely picky when it comes to this stuff, so it probably won't bother others as much. Both my wife and I prefered the old 'touch sound', but I am sure we'll get used to this fast. Graphics look great, everything works, looking forward to see what else can be done.
