ESRI take note. But there is one problem with those products you just mentioned I don't like the fact that I have to remove those products manually & then install the updates after. I prefer an automated remove of the previous version & install of the new version.
According to their website:
Get more for your money. Don't waste money on old-fashioned, overpriced, unreliable GIS products in a tough economy.
I guess their costumers were led to Free and Open Source GIS (QGIS, gvSIG, uDIG, GRASS...just to name a few)....they should have been a bit more careful in what they were suggesting their customers!
In regards to those products listed above some of them are made available through the OSGeo4W installer which I find has made upgrading quite simple. I use QGIS through this installer and the option to upgrade, roll back or remove is quite good I think.
It sucks that Manifold has stuffed around so long, but it looks like people are exploring alternative solutions which I think can be beneficial to all........in the long run. Manifold at one stage was on my list of alternatives to ArcMap but due to this scenario has been wiped clear off the page.
