Google services on iOS are great, the gmail app is miles better than the stock mail.app, you get push notifications faster than filtering it through mail.app. Google Contacts work great as CardDav and calendar works perfectly as CalDav set up. On thing which i use alot during the day is Gtalk on my desktop but it doesnt sync well with any IM app that i have tried, on an iOS device you have to stick with the app you are using to carry on the conversation you can’t go from desktop to phone/tablet and read all the messages you have been receiving on the desktop. A GTalk app would be the final piece in my iOS google jigsaw for me. I look forward to the next Nexus, maybe that will be venture back into the android world since the T1.
