Managers adding portable computers to their hardware menu must also decide what software to offer. At 100 small and midsize companies, here's what off-site employees tap into:

Type of information accessed by portable-computer users Percentage of users
Database files 66%
Electronic mail via the company network 56%
Sales/order entries 40%
On-line databases or news services 21%
Electronic mail via a public network 16%
Relational databases 14%
Other 7%
Note: Total equals more than 100% because of overlap of tasks.
