Just seen this: Official Google Blog: Winter cleaning
I don't use google services but for those who do, this is just crap. Exchange Active Sync may not be "open source" but it is much better than the "open" alternatives google are pushing.
1) Supports full push emails
2) Supports business settings (i.e. encryption, require passcodes, etc...)
3) Supports remote device wiping
I'm just glad I'm using outlook.com/office 365/exchange and Windows Phone 8.
