Elliot, > Getting rid of spam is a HUGE benefit. Heck. What I've found > so amusing is that people seem to upgrade their Microsoft systems just > 'cause, with no perceived benefit, but merely protecting from Bit Rot. Many folks update their MS software (Linux, too) in the hope they will get more stability / more security / more seatures - not becaue of bit rot. Updating mail clients does not seem to be a huge deal - manypeople update their OS / browser when prompted. Majority of my friends & family use a web browser to access private mail. Companies would have interest in upgrading, if it helped also with viruses & security. John
