Xobni – useful but may have to go
I've been using Xobni for a couple of weeks now since their launch at the TechCrunch conference. It has a couple of features I really like – for example, displaying the last email you looked at when switching Outlook from Mail to Calendar. As simple as it sounds, this is a great feature as it saves having to remember the date and time of the meeting you are about to add to the calendar or having two windows open for Outlook – one for mail and the other for the calendar.
Unfortunately, since installing Xobni the performance of Outlook has fallen dramatically and from time to time Outlook hangs consuming 50% or more of the CPU. After a few of the hangs I'm beginning to believe there is an interaction between Xobni and X1 – X1 is the fast-as-you-can-type search tool that makes search for everything (mail, contacts, files…) so fast that it's a corner stone of my workflow.
I'm going to wait for another release update of Xobni before deciding whether it stays or not – I hope the interaction problem gets nailed but in the limit, Xobni is a nice to have and X1 is a MUST have for me.
