Inbox2 a desktop client application for combining all your Emails and Social messaging in one place. It can fetch all the mails from Gmail, Hotmail, Yahoo, AOL, MS Exchange mail servers, IMAP and POP3 account as well. Not only that It can receive and update to your Facebook, Twitter, Yammer and LinkedIn updates and messages.
First thing impressed me is the simple interface and initial setup for social accounts. Setup for your social accounts is so easy, just simple clicks. Once you have setup, it will fetch all the last 50 messages, contacts and attachments from your chosen accounts in separated tabs. (There is an option to load all the message in Inbox2). For now, Inbox2 is Free application and available for Windows only.
