I've told her how I feel about Suns at home and some of the issue I see that are important to home Sun users. She would like to talk to some of the folks on this mailing list to see how you feel about such topics as: - What is the appeal of having a Sun at home? - What applications do you use your Sun for? - Who do you work for? - What do you like or dislike about a Sun as a home machine? - Would you switch to something else? Why? or why not? If you're interested in responding, drop Janet a note at: observer@pcinews.lonestar.org -- or -- {cs.texas.edu, execu.com, texbell}!pcinews!observer Thanks! --Dwight D.
