1. Beta Offline acccess i.e. Gmail access without a network connection, early reports are that it actually works better than the online version!! If this claim is true it will be yet another nail in the coffin for client based mail (outlook etc). Why would anyone not want to use web based mail?2. Domain aliasing, you can now use your @unilever.com, as an alias for your gmail account. What this means, 1. You can use an iPhone without have to have a VPN tunnel or corporate cert installed, 2. Contactors and 3rd parties can be divested of their corporate devices and email accouts (reducing licencing and hardware provisoning requirements). (Note: You do need to authenticate to prove that you own the original account, so you can't spoof email addresses, when you send an email the reciever sees in the header that it's 'sent of behalf of' - which in a way is a good thing in my view.)
