I am down to a single Google app, and that is gmail, less for the reason that I am particularly enamored with it, but more because it seemred, in the traditional google way, to be the best game in town. my searches are done through startpage, which is a lot like duck duck go, except they seem to work (at least for me) a lot better.

I don't think their spam filter is that good any more. It used to be much, much better, but in the past 6 months or so, I have simultaneously had spam in my inboxes, and legitimate messages in my spam folder. This has become the norm in the recent past.
Now I on the other hand, use the web interface almost exclusively. Thus, I would probably be a good candidate for Kolab Now with their Roundcube integration...
Unfortunanately, I have a work iphone, so leaving Android is no problem for me. Then again, I trust it with my data as little as possible...My data all goes on my Nokia N900, my "brain prosthesis," as a friend of mine refers to it. It doesn't have a SIM card, so it is not a phone, just a portable computer, with my books and media on it.
So gmail is the only hurdle left to leaving google (well, that and youtube, but I never log in to youtube, so there is that).
@bryanlunduke, I have not yet read your articles, how is Kolab Now treating you? Is it a worthy replacement for google? At this point, I'm willing to pay to keep my data out of google's hands. I have a free protonmail account, but it is still in beta, and seriously not "there yet." So I'm still looking. I heard Aaron on a podcast talking about kolab now a while back, but never looked into it much. What are your thoughts?
