Gnome Mail is a nice alternative for people that deal with many mail accounts but don’t want to use a “heavy” application like Thunderbird or Evolution. It seems more like a “poster” App, where emails are treated like Twits or FB “walling”. Besides do not forget that GOA has Twitter and Facebook support.
Of course Gmail (Gnome Mail!) features a chat client and support attachments.
