I want to study almost anywhere (in my company, in restaurants, in cab, in rain, while walking). I want to update my resumes in mobile and want user friendly mobile. Should I buy Windows Mobile OR Android Mobile? Should I buy Touch Screen OR Quarty keypad? My budget is 10K to 20K. I want as cheap as possible in real. I am thinking to buy Nokia Lumia 800 (Windows Mobile) (Rs. 18K). Or should I go for Sony Xperia (Android Mobile), HTC Desire C, etc. Please suggest which one will be best.
