Thomson Publishing just sent me an upgrade invite for Endnote XI. They're really starting to tick me off - they pump out a new version every year and charge a fortune to upgrade, but release precious few point releases that address bugs through the year. I *think* they've released two for version X (apparently I have the final version and it's 10.0.2). Anyway, I just checked my records and I purchased the upgrade to v.X on October 26, 2006 for 2/3 the price that I'm being offered today. They're offereing one new feature that looks interesting: Groups.

Drag and drop references into groups just as you do with playlists of music.However, there is a world of difference between interesting and forking out $90 for an upgrade... There's also a world of difference between looking interesting on paper and having any real world relevance. In my case, with over 5000 entries in my main library creating groups would probably be more bother than it's worth. I'll be sitting this one, and probably several more, out.



. But I cannot live without it...indispensible for my PhD thesis and papers. 
) After the exams are over I'm going to have another go at it without the pressure of actually trying to meet a deadline and will be able to dig through its options, but my initial impression as an undergraduate student it will, i think, meet all my needs for sorting tagging categorizing references and so on that i need and of course it can be used as a journal keeper to do list, all of those sort of things, though you wouldn't buy it to do those functions alone, once i've moved on from studying (if i do, might retire as a student yet lol)
