 Previous to this, Palm only produced PDAs running the Palm OS (as did the first versions of the Palm Treo).HTC manufactures up to 80% of all phone enabled Windows Mobile devices for other companies (including HP and O2), as well as many non-phone Pocket PCs (for companies such as Dell, HP and Fujitsu Siemens).HTC is now marketing Windows Mobile devices under their own brand, as well as that of Dopod.
