Do you normally use email, calendars etc via the browser? Just curious as you say you've not found slick versions elsewhere and I'm not sure what that means to you. For example, I hardly ever access these things via the browser so 'slick' for me is just fast sync between devices.
Yes, I access email, calendar and contact via browser only on all desktop computers I use. And on phones and tablets I use native Gmail and Calendar apps and have contacts synchronized everywhere.
I haven't used desktop client for private mail for years, and I don't see that changing, because of the privacy and security concerns. I'm willing to let NSA or some other faceless foreign entity snoop my email if that will prevent people around me that can get hold of my phone or computer from reading my mail.
