Same here. We have SBS 2003 and mostly XP / with a couple Windows 7.
I uninstall and re - netsetup workstations that are getting pokey. Otherwise just the occasional crash - and none on the server. I install program updates from server and try to do most of the forms from there too. (I login as myself and run on server). In the course of the day, I will update from workstations. I learned there sometimes are forms to update even if the button is green.
No, it is not as fast as 2011. Nor does it give you the right pages when printing. But for now, happy we didn't switch (with 10 years of ATX archive files / databases). And not really any time to retrain users.
