I've never used a mouse with my MBP, and for me the force touch trackpad is great. The whole pad is superior to any others I've used - I rate the pads on my Lenovos as virtually useless - and force touch enhances it. I can click anywhere on the pad, which is a major improvement over others, and the two (adjustable) force levels give extra functionality. Not too much extra for me because I don't use much Apple software, and certainly my 2011 edition MS Office is not coded to support the function, but in Safari and Chrome when displaying most (not all) web content pressing down to the second level on a word brings up a Wikipedia definition. Overall I would say the trackpad is definitely one of the best features of my MBP, and in over a year's use I've never even considered plugging a mouse in.
