No worries with using a small laptop. I use my RSPdx along with a Microsoft Surface Go tablet. Works great. As to software, most any of the available windows-based programs - SDRUno, HDSDR, SDR Console, SDR++, etc. will work well on a windows tablet. If you are using an android tablet, there is one available program called SDR Touch. IMO it isn't very good as compared to any of the windows offerings. Have fun!
