TBH I dont own a mini but I have used it and it seems fine. online reviews are also decent if you go above baseline 8Gb. but thats targeted towards mac users which are already in higher price bracket so not too bad. plus its better if power consumption and noise level.
overall I feel that there is enough integration density in processors that the laptop form factors will be good enough for most common (& semi advanced) uses. so this seems like an odd decision to move out of that market (technically) but if you factor in business then it starts to makes sense.
