Trillian -- Version 3 Released

Trillian version 3.0 was released yesterday (more info here, slashdot picked it up here).  I don't exactly remember when I started using Trillian exclusively as my main messaging client (a few years now), but I know that since I started I haven't looked back.  It's also one of those rare pieces of software that I didn't mind shelling out the extra 25 bucks for (even though there is plenty of free (as in speech/beer) packages that accomplish the same thing).  Yes, there are some incompatibilities between the Trillian client and the respective messaging clients (AIM, MSN, Y!, and ICQ...I don't use IRC so I can't comment on it)...I get some file transfers that hang, webcam usage pretty much doesn't exist (I can't remember the last time I needed that anyways), and there are probably other ones that I don't know about as I haven't used any of the individual clients in some time...but I'm really not what I would consider a hardcore messaging type person.  I have approximately 150 contacts, and the majority of them are business related, so I really don't need all that extraneous crap.  Basically, it supports everything I need (and perhaps more than I need and I just don't know about). 

The main selling points for me are:

• Single point of sign on...one application, and a fairly modest footprint to boot.
• Skinning.
• XML configuration...if I install Trillian on another machine, I can just copy over the necessary XML files and I'm off and running with an identical install on every machine I need it on (mainly, contact grouping).
• I can dock my contact list to the side of my screen...this works great at 1600x1200; I can monitor my contacts without having any annoying pop-up "toasts" to distract me.
• Container grouping, i.e. I have all of my message windows (or any type of window actually) in one container with a tab based interface.  This cuts down on desktop clutter drastically.
• Plug-ins.  Pretty much any (3rd party) app these days that doesn't support custom plug-ins will never make it to my machine.  From my docked Trillian window, I can monitor mail for each account, monitor stocks, monitor as many RSS feeds as I'd like (I keep about 10 crucial ones loaded up), monitor local weather, create tasks, etc...each via a plug-in.  There are plenty of other plug-ins out there, but those are the main ones I find useful.
• Message history.  Yes, most of the other clients have finally caught on to this, but Trillian reigned king in this area for quite a while.  Information management is a crucial part of anyone's day to day ordeals, and like most I receive probably half of my info via messaging...so it's good to have a trail laying around somewhere.
• Consistent, simple unifying interface across all messaging mediums.  Again, I don't need all the bells and whistles of each individual client, just give me what I need and make it work...which Trillian does a bang up job at.

So what's the point of this post (besides giving accolades to a great product)?  The million dollar question (well, 25 dollars in this case):  Should I upgrade to the newest version when the previous version works great, and even more, should I shell out another 25 bucks (which I don't mind, so long as it's worth it...this is a major release, so it's to be expected) for the Pro version?  As always, I value feedback.  Anyone gone through the upgrade process?  Any snags?  Any killer new features?  I do know one thing, I absolutely will not upgrade until a port of the great Aikon3 skin is complete (which should be soon from what I hear).  Sounding board is on.
