It's indispensable to anyone who needs to regularly connect to services on your LAN. I RDP to our internal servers/PC's all the time on Android/iOS, as well as various other internal only services. Have been doing this for years and it's just utterly amazing that this is not possible on WP.
What's wrong with IMAP, my Gmail account syncs just fine using it.
Gmail is a special IMAP account specifically setup for Gmail on WP. Try using standard IMAP - it forces the names of your send and delete folders, and completely doesn't handle subfolders, the ability to copy between folders, to name a few showstoppers and unbelievably, this has been the state of windows phone IMAP support since the first windows phone version.
Notification center that everyone is crying about is in the 8.1 update.
Ah, the mythical *2014* 8.1 update. I won't hold my breath.
In the meantime I just love seeing a notification popup but just missing reading it, so ending up trawling through every app to try and work out where it came from.
This is so ridiculously far behind the standard. Every now and again I dust off the Lumia to update it and see if features I've taken for granted in Android and IOS for years have finally been added because I happen to think WP is *potentially* a great platform, and every time I find myself amazed that, no, the IMAP support is still as crappy as it was in WP7, and no, you still can't do basic things like connect to an office server over VPN.
