I've had my Z Canvas now for 16 months. Since I got into tablet PCs this is the machine I've kept the longest. I spent a pretty penny on this model used, with warranty still in affect through 2/18. When at home it's connected to a USB 3.0 docking station that powers 2x1080p touchscreen monitors, speakers, keyboard, printer, and when I unplug it it goes with me to class for notetaking. My use case allows for it to last throughout the day, as I can plug it in at lunch and most of my daily activities are in OneNote or Chrome. I really do appreciate the power as OneNote can bog down when importing massive lecture PDFs and every second counts. I have no idea if I will upgrade soon. If I did, I think I will go back to a convertible form factor and something with a better keyboard than the Z Canvas'. But as of this point, I think it's safe to say I've been really happy with this machine. It successfully consolidated things to a single computer, and for day to day usage, I see no difference compared to the old i7-4770k mini-ITX build I had overclocked to 4.6GHz. Minor slowdowns in photoshop and illustrator, but nothing worth complaining about.
