There was few news about it but between the various improvements that Google
staff has done on Gmail, one of this could have a big impact on our every day
business: Gmail
Mobile.
Now you can access your Gmail inbox also from a mobile phone that has a
browser able to open HTML pages (and Gmail will feets your screen resolution and
size). 
Obviously, if you have a modern web-enabled phone you can access your Gmail
mailbox also via the standard interface (exactly like a browser on your pc), but
I think that the mobile interface could be more fast and with a better
resolution on a phone screen.
Reaching your mailbox also from your phone is a must today and this new Gmail
feature is really welcome...
