Not to be a killjoy but: Personally I would be careful in the wholesale
replacement of electrolytics with Tantalum caps. Tantalum caps can not stand
the inrush current that electrolytics can which can cause the Tantalum cap to
fail. They require some series impedance from the voltage source to the cap so
as not to exceed the inrush current.
I agree it can be done in some places just be careful.
Couple of references!

Subject: Re: [TenTec] OT: swapping a Tantalum for a Electrolytic
IMHO There is zero problem doing that. The Tantalum cap has a better ESR
rating and better performance at cold temperature.
