It's been about 10 years since I used my surface pro at uni. The main problems that I remember were

1) top heavy, because all the hardware is on the screen portion, so it's difficult to balance and use it on your lap

2) lack of processing power due to the form factor and thermal limitations

3) lack of touch friendly windows apps that can make it truly useful as a tablet

1 probably can't be helped, but 2 and 3 should definitely be better now especially since Apple silicon and iOS exist, if they choose to make something like this...
