That Picolog is dying is sad to hear. The related products, TC-08 etc, are well spec'ed and easy to use with Picolog.
it is however good news that Pico is going to do something useful with measurements. I assume that Pico does not want to rewrite Picolog to make it universal for all products? If so then it would be better to make the measurements acessible to 3rd party dataloging software. The most obvious is the free NI Software Express LE. Also very affordable is the UK Windmill logging software package which I use. I guess every client will have their own favorite, but since it is very likely that Picoscope measurements will be logged with data from other instruments, Pico will have to chose some industry standard if it does not want to go through the pain of developing a universal open logging package.
Good luck and poste haste!
