FWIW, I never considered that a serious limitation. On my phone, I don’t want to read email. It’s a sub-par experience, especially if you’re used to Sup/Gmail/Notmuch. You can’t just go back to “regular” email clients anymore :).

As for using multiple computers: with sup I used to run it in screen and attach that screen session whenever I needed it. With notmuch, I can just tell it to run notmuch(1) on a remote machine and even use a local UI.

I do some email using my phone when on the go, and although I'd like a better sync experience, it's not a showstopper. OfflineIMAP (buggy as hell, but works) can sync unread and flagged/starred status, which is the most important part. In a normal day where I mostly use notmuch, I just batch-archive the day's messages. I don't like the latency of using a remote notmuch, especially when going through a string of 5MB log files (remote debugging a user's mis-configuration) on conference wireless or while tethering.

If you haven't already considered mbsync as an alternative to OfflineIMAP, I suggest taking a look. I also found OfflineIMAP buggy (many years ago) and mbsync has been syncing my mailboxes reliably since. http://isync.sourceforge.net/ I say this as the author of a program that runs mailbox syncers like mbsync when there are changes to sync (mswatch: http://mswatch.sourceforge.net/).
