I'm sure ESRI runs a special camp they can send you to for re-education :) It does absolutely everything! Which is why it's so hard to pry it out of the hands of a dedicated ESRI fan... if you spend the time on it, you'll find there's not a problem you can't solve with this one universal tool. You can use it as a database, you can use it as a graphic design package, you can use it for map algebra, for network analysis, for data integration (using the Interop Extension), as a programming environment, as a capture package, for image analysis, for data processing. Of course, it will be slow and sub-optimal at solving many many problems, but that doesn't take away from it's universality. Things it does really well, well enough to be considered a category leader on meritorious grounds: * Ad hoc cartography. * Ad hoc analysis. * Data exploration. Having all those tools in one place at your command makes trying different possibilities and approaches easier. Take the conversation away from GIS. Let's say you're a statistics analyst. You're a wizard at SPSS. I show up and say, "hey, you should use R, it's just like SPlus, a really powerful statistics package, only it's open source!". Do you switch? And that's a switch with almost perfect feature parity. Unlike web services, which can be chipped away at and operational people don't have a really visceral attachment to (a web page, is a web page, who cares what software serves it up), ArcMap is an in-your-face operational tool, that people have years of mind-share invested in. You'll pry it out of their cold dead hands. Maybe. And ESRI can and does use that loyalty to push other less-superior software into lots of other places in the IT space where the decisions are controlled by loyal devotees. That has been my experience, in any event. Is ArcMap "all that"? It is to the people who have learned the ins and outs. Why do people still use MSWord, when OpenOffice will do what they need? Corporately it's the safe choice, and that 5% of users who actually use the extra features in Word can drive the decision to take the "safe", full-featured package instead.
