If she uses messaging more than web (sms, text, IM, email), then a blackberry is so much more comfortable and efficient to use. Great keyboards, great messaging services, no fuss sync, 2-clicks picture sharing, native MMS support, etc.

The web browser is not on the same level as the touchscreen driven ones, but it gets the job done. I've made posts on this forum through my BB Bold no problem.

A great majority of the female users/colleagues/friends/acquaintances/family that I know of whom have used iphone and/or android and also blackberry MUCH prefers the BB for messaging.
