The new 990 is so busy with knobs, etc.......
You can NEVER have too many knobs on a amateur transceiver.
You can, however, have way too many levels of menus to deal with. Between a knob and a menu entry to control an option, give me a knob anyday! Instant control and no stairstepping of levels. I really hate it when I can't get to the desired level for something because menu level 3 is too low and level 4 is too high. Unless the designers include a large number of intervals in the menuing control, the adjustment sometimes is just too coarse.
