Buying a house. Husband in Prague. You are a life saver. Made filling out standard forms for buying a house and getting signatures attached a real breeze.

It's been very pleasant as a university student. One thing that is quite annoying is the scrolling feature - when I scroll on my macbook pro it doesn't really work well. Overall, this is perfect for annotating my lecture slides and readings. As a student, I find it a bit expensive ($72/year) - maybe there can be some incentive for students?? :)

It served my purposes It served my purposes. There were a few instances where it would not properly let me check a box. Also, inputting dates, did not always work as expected. I was not always able to manually type in a date. It forced me to use the calendar. Sometimes. It's a good tool.
