James Robertson is asking people what they think of Store on his blog in this post. Regardless of what you think about Store, you have to like the fact that they are asking the community what they think about it.
My personal opinion is that Store is pretty good for remote work (much better than Envy). I’ve used Monticello and it seems pretty good too. I agree with other replies that Parcels in VW are behind the times. I’m leaning towards Monticello since it works so well for Squeak and would bring two Smalltalks closer together. It would be very cool to continue to have things like Seaside and Monticello bring different Smalltalk dialects closer together.
