My Bible tells me....
to call no man a fool.
Who is this "person?" (you substitute fool if you dare!)
Dynamic integration of multiple devices
Absolute ease of user interface
Multiple sources of community help
Multiple OS support
Wonderful people like Mr. Kovid and his peers
And this "person" complains about the program?
Why don't you, Sir, submit constructive suggestions to Mr. Kovid or the community and wait, see, how improvements are made with this wonderful program?
