I've been fond of Smalltalk since 20 years but have not the occasion any more to develop with this great language/ide :-(
It seems that people after having tried java, c#, ruby, python, groovy, grails, ruby on rails,..., to solve their development problems reached conclusions that everything or almost was already thought, designed 30 years ago with Smalltalk.
Smalltalk is again in the front of door with Seaside, ther continuation framework firstly built in Squeak.
An IBM internal project still focus on Smalltalk for adapting Smalltalk to the eclipse platform through the STDT project.
I hope that Smalltalk will be back on the market, because it still the best architectured language ever.
For information, below can be found a list of Smalltalk providers :
