The setup of the phone was very easy, I just had to pop in the SIM card from Airtel in India, setup the GPRS settings and then I entered the details for my google apps account. This becomes the primary google account for the phone and all the other stuff like calendar, google talk etc. are used from this account.
Following are the most notable interesting things that I found about the phone.
- GMail
- Google Calendar
- Google Talk
- Read only integration of Google Docs
- Google Maps with street view
- Contacts integration with GMail contacts
- Email app for additional email accounts (POP3, IMAP)
- Android Market
- Barcode reader app and its intergation with Google search
There are things that need improvement and most probably would be improved in future.
- GMail (not the Email) app needs to have option to add more accounts. It is very common to have one GMail tied to Google Apps and another one @gmail.com. Currently one needs to choose one of these as GMail while other one as to be setup in the Email app. The Email app does not have option for Archive and some of the other GMail specific features
- GMail needs to have option to accept and reject invitations sent through the calendar
- Google Talk needs to integrate with Orkut and may be at a later date Facebook
- Docs should be editable -- probably limited by the processing power on the phone but would be good to have
- Service that would generate notifications for feeds registered in google reader. For reading itself the webbased stuff is good enough.
I will add most stuff as I use the phone more. Overall I think I like this phone and would recommend to anyone who uses google services. For users in India I would suggest rather than buying T-Mobile G1 and worrying about unlocking etc., they can register themselves with android market and buy the Android Developer Phone 1.
