Will this affect the native iPhone app? http://thenextweb.com/google/2015/05/30/googles-gmail-api-officially-gets-push-notification-support/
No, unlikely. Unless Apple and Google work together.
I am looking at office 365 or iCloud for email. I already have 20 gigs on iCloud. I just did not want to let apple nor Google own my email but .99 cents seems like the best solution. I feel like I am committing my self to apple fully just like I did with Google befor.
I think your right Dropbox is the way to fly for documents. I use it with my clients and my accountant it is so easy and secure.
i think gmail will be moved to a junk catch system for me sadly.
iCloud doesn’t always work well with third-party email applications, in my experience. I’ve had ample of connection problems over the years on my BlackBerry Z10 and with several email applications on Linux. That shouldn’t be the case if it was fully compliant with standards. iCloud also has a pretty bad web client which is only sufficient for casual users but no one else. Outlook gives you a much better experience and they give you an Exchange address with ActiveSync.
If you would like to consider something else altogether, you might want to have a look at Protonmail. They are still in beta with a reservation system, but they are releasing their native iOS and Android apps soon and their web client is due to be overhauled in the coming months. The great thing about Protonmail is that they don’t plan to serve ads and they encrypt your mailbox, meaning no spying or tracking. The downside is that they currently rely on a web client (and a few mobile apps soon), but offer no IMAP or Exchange due to the encryption. My hope is that someone develops a plugin soon for their open source PGP-like encryption (they plan to do this for Thunderbird anyway) and there appears to be a dedicated community that could pick this up. Might be worth the wait.
