I'd been pitched for Linux based Motorola phones last year by The Mobile Store fellows as virus free and all. Afraid the model was low-end with real linux advantage.
I have not been able to find any good Linux based PDAs and the ones that i do find hav gone out of production. Whereever u go, the store guys will pitch for Windows Mobile only. Symbian or Android phones have entered in a big way, but not in India yet. Awareness is definitely lacking but so also the enthu from retailers. I mean if i m selling a product as a retailer, i would like to see what i get from a product (when selling a milk pack i get a rupee from it, windows out of 4k i might get 100 bucks) but not with linux. So retailers are not interested here unless they are linux guys themselves.
