I haven't used Acrobat Reader in Windows since I discovered Foxit Reader years ago. Much smaller than Adobe and has more functionality. Plus it let's one add typewritten notations to a PDF file....and it's free.
A lot of good software packages in this list though. I'll have to install some and see how they work.
Please report back here your findings. I am quite familiar with some of the apps listed above, but others I have not heard of before.
Also, if you have other suggestions, feel free to add them to the list!
