Why do people make a big deal of this Outlook plugin. I remember using Eudora email and back in 2001 Eudora mail had some of the same features.

Not all the features but the majority. I hate when people make a big deal out of a basic Outlook plugin. I give them credit for building a good product but I am sure microsoft could develop something better, after all they own the source code of Outlook

Because it's a yc combinator startup and their are lots of yc combinator fans out there.

Don't you see that many of the startups are boosting each other (which might not be a bad thing) and are using each others services to improve their chance of success.

Because millions of people with money use Outlook for hours every day and Outlook hasn't improved much in years.

What would be really cool would be if Xobni could write my emails for me and keep in touch with my contacts. I really kind of suck at that.

And not only with clients, but also send sweet nothings to your girlfriend, endearing and respectful letters to your parents, stern and firm letters to the IRS, and so on. And make coffee.
