I’ve been long-time Gmail fan, having used it from the very early days, for almost 5 years now. The key reasons why I switched and have stuck with the service ever since were the productivity boosters, first of all:
- Threaded conversations
Google did to email what all new product teams should: throw away all known concepts, start from fresh, figure our what the system should really do, instead of delivering a customary system with minor improvements. Instant success. Instant Customers. No, correct that: instant users. There is a difference. Apparently not everyone likes “radically new”.
