Magic Email Sidebar Xobni Now Available for Gmail

 Once you've added x-ray vision to your email inbox, you'll never go back to life without it. The latest service to offer just that is Xobni, a high-profile startup that brought its Outlook plug-in out of Beta status a year ago next week. Today Xobni comes to Gmail and it looks really nice. The first 100 ReadWriteWeb readers who visit this link and enter the code XOBNI-RWW will be provided access to it. The company says iPhone and Android versions will open for testing within 90 days.

Xobni competes with Rapportive (my favorite to date) and Gist, which was recently acquired by Blackberry company RIM. Another service called eTacts (site now down) was recently acquired by Salesforce. Xobni was funded by Blackberry Partners a year ago, but remains independent. Check out the screenshot below to get a feel for how it looks, what it offers and how it's different.
