Looking at moving from the iPhone 5 to a HTC One - what is the IMAP, CardDAV and CalDAV support like? I'm using the iCloud and wondering what the support is like or whether I'm better off migrating to Google's own services instead.
IMAP works great, couldn't speak to the other two as I use Exchange ActiveSync which is awesome.
I don't think you would regret moving from the iPhone for a second, a new One should come with Android 4.2.2 or will at the least have an OTA available and makes it in my opinion the best smartphone out there.
The only shortcoming Android has compared to iOS is the automated backup/restore stuff but HTC has done a decent job at fixing that by backing up everything to a Dropbox account and allowing full restores from that. Much better than Googles effort at it.
Just bought it an hour ago and honestly this is an underrated phone given that as a dyed in the wool Apple fanboy it definitely is the 'iPhone replacement' at this point. I've moved my stuff over to Google, downloaded WhatsApp and ASB Bank's online banking application - everything is working beautifully and the signal is even better as well which is kind of strange.
As for the experience using HTC Sync Manager on a Mac - working wonderfully and stable, and OS X even detects the Android phone so I can tether whilst I wait for the VDSL2 installation to take place next week on Monday.
I've decided to move things over to Google - everything is working great and migrating the old emails from one IMAP to another in Mail.app is as easy as dragging and dropping from iCloud to Google :-)
Btw, great sales experience in Upper Hutt so someone at Telecom should shout them a free pizza and a 6 pack of cider :-)
