A:Answer 1. If you have Office 365, then you should be able to use that account on this device if you deactivate it on another device. If you do not have Office 365 but still have an (unused) license key, you can install most versions of Office on this computer. Please check with Microsoft and consider the following links:

2. I have encountered no issues while using MS Word 2016 on this device. The Lenovo brand is well-known for their comfortable keyboards, too. You should be able to use MS Office very comfortably on this device and for extended periods of time without hand-cramping. If you have larger hands (like me), I would strongly recommend buying a USB mouse, though, as the trackpad is very tiny for comfortable use.
