I watched a few of their videos, and I believe that the protocol decoding is done in hardware,
as it is blazing fast!
This is really a strong contender
250Mpts memory, >330.000 waveforms/sec, FFT with 4M points, protocol decoding in hardware
It has support for many protocols, including RC5 and RC6 infrared protocols.
So, you no longer need to use your sound card for capturing and interpreting this stuff
Their 6 1/2 multimeter for 800 EUR is pretty neat too!
