Thank you AlexTinsley, that was very helpful,
I was investigating about my current laptop system and the Expresscard and it is not there. So my options are to buy anoher laptop around $1200 with this slot available or to buy the SL-Dante-Mix Dante Card For Studiolive like below:
but I am not sure if that card is compatible with my current system, is that device use a common network port?
I have a computer toshiba with windows 8.1, 64bits 12 GB RAM, intel Core i7,
Please let me know, many thanks in advance
