I find the trackpad to be quite good compared to most other Windows PCs, but it is on the small side. I haven't tried the SP4 keyboard yet where it is slightly larger.

The touch capability is interesting in that I've found that I've begun using it along with the pen more and more over time. The pen has really grown on me as I've discovered more ways to put it to use. For the first year that I owned my SP3 I rarely used the pen, but now I use it almost every day. Being able to switch from full on tablet and pen back to keyboard and mouse mode is pretty killer and I plan to continue using this form factor for the foreseeable future.
