To avoid a large download, you can
test drive Mappoint live using Remote Desktop technology to get a rough idea of what it's like. Note:
Streets and Trips contains a subset of
Mappoint's features. As long as you avoid all the data features and use only the mapping and trip planning features, it'll give you a fair idea of what S&T is like. Also note: it'll be very laggy over satellite.
I wonder why there isn't a company that mails you DVDs of large downloads. This would be useful to people using modem, slow DSL, satellite, or other rate-capped connections. I've never found one, although I can understand why such a service would not turn a profit.
