One way of gauging this factor is
to look at the number of people             Companies Building Mira-Enabled PCs
on the respective project teams
at Microsoft. The Tablet PC team            Fujitsu           OEM (Japan)          See above
has around 200 people; the Mira             NEC               OEM (Japan)          See above
team has around 20. However,                Panasonic         OEM (Japan)          No webpads
