I didn't feel the jog to be an issue. Although I've only used it in comparison to 1000s /2000s. Doesn't feel that different IMO. Other diffetrnces: -link: can connect 1 USB and access it from both decks or connect a laptop with rekordbox as track screen -screen: tilted and larger -slip mode: in vinyl mode, song keeps playing underneath when your scratching / touching platter, so it doesn't fall out of time -quantised looping - snaps your loops to nearest beat to help keep them in time -900 has a HID mapping for traktor and serato. The 850 has HID but only serato mapping atm -not sure what the 900 is like but the pitch fader on the 2000 has less friction you could say -you can use wide pitch adjust mode in All modes on the 900. The 850 only allows you to do it in cd (and midi I guess) mode Even with all that though I have 3 850s and are extremely happy with them
