I have a refurbed SP1 that I bought out of curiosity. It's decent. The keyboard is passable. The touch pad is horrible. The one position kickstand has promise as demonstrated by the third revision. The Wacom pen system is good. I am a casual user of the pen, and it works well enough. I was at the MS store to check out the SP3. I am aware of all of the existing issues. As a lefty, I gave the N-trig a try with the Metro OneNote and I encountered problems. My palm kept triggering the page selection on the left hand side. Also the pen cursor was jumpy. As I was writing, the cursor would occasionally jump creating lines out to the point it jumped. I didn't have the jump issue with the Wacom. The above issue could be a killer for me. The pen is a major selling and disguising feature for this device. I preordered the i7 version and I am worried about heat issues as well. To the lefties that have the SP3, how is your pen experience?
