Bernard posted saying that he’s made the move to cut out his use of Microsoft Outlook, now solely relying on Gmail for all his email requirements. He states the benefits of better (for him) search, the simplicity of having everything in one app, better spam protection and the ability to use Google with corporate domains all adding up to a good business case for Gmail.
I’ve been using Gmail pretty much exclusively for my email purposes for a few years now – but there is one barrier to uptake increasing – especially amongst mobile users. I use my smartphone pretty extensively and while I can access my Gmail and Google calendar on the device via the browser, it’s be really useful to be able to see email and events within the native Windows Mobile device, and at the same time be able to sync my contacts between Gmail and the device – sure this can be done by using various third party offerings, or by making an intermediate sync to Outlook – but native syncing direct from Google to Win Mob would be really useful.
Similarly another important feature missing from the most likely Outlook competitor is offline access. It is a long-time-coming feature that will really increase the utility of Gmail
Having said all that though, the fact that a small business can have Gmail using their own domain, that they can bypass their own ISPs mail servers to decrease traffic quantity and that they can obtain "enterprise grade" spam protection all adds up to a pretty compelling argument to offshore their email to Mountain View.
