Started out sceptical about the keyless, but now really appreciate it, though I think it is essential to have a non-electronic spare key cut just for unlocking seats, satnav, etc, so that you can keep the keyless fob permanently in a pocket, as otherwise there is a risk of losing the one and only electronic key (apart from plastic emergency key).
The quick shifter I really don't use much. I've tried it, and on upshifts IMO is only really good under hard acceleration which is not really my style most of the time. If short shifting or making more leisurely progress it can be quite jerky. I might use it more for downshifting, particularly on roads like dual carriageways with frequent islands as it can get a bit tedious going down through all the gears, though the bike down shifts very nicely manually with a bit of throttle blipping anyway, so it is no real hardship.
The only problem with downshifts is that you have to have the throttle fully shut for it to work, but this gives full engine braking and can slow you down quicker than you really want unless you are leaving your deceleration to the last minute - so again IMO really more suited to when pressing on. I often ride with a pillion, so I more often change down early on a part throttle to avoid throwing the pillion forwards, with a reasonable gap between each downshift, and it can't really be used for that style of riding.
