tons of common issues with the sp1, you're maybe not using the unit hard enough to break the functionality with overwear and stress, but the sp1 has tons of engineering defects they corrected in the sp2. The sp2 still has some, but not as many.
Just hope the Sb3 solves the issues the 2 and 1 had, but that price is absolutely insane tbh... better grabbing an iPad Pro +pen for drawing, the surface can be a bit iffy with drawing due it its magnetic wobble when using rulers... it can't draw straight lines off reference, its a shortcoming in the digitizer / pen tech to this day.
Theres a ton of engineering issues, software to hardware to just quality of life - while I love how MS has become the new apple with innovation, its still not as good of a work unit vs apple.
Also, while I love the surface pro the most, and have been with Microsoft since the SP4 onward, ive gone back to apple recently and missed the quality here, minus the bad bootcamp drivers and gimped system in windows, like no Igpu.... its still nice to go back to osx.
A lot of great design software on here, and this trackpad is just worth it... nothing comes close.
