Don't get me wrong - I love Windows 7, it's a really solid platform. Some of the issues I've faced: The Citrix Xenapp client is very buggy. Sometimes just fails to load session with no error - just looks like it's launching and then stops, sometimes freezes mid session. On reboot the client launches mutliple sessions and it takes 5 or 6 times clicking cancel to make the client pop-up stay minimised. Adobe Acrobat - Sometimes need to save twice, sometimes saying it has saved only to find the PDF a blank page or pages. Sometimes just fails without providing error. MS Office applications saying that they cannot save whilst working on a current document forcing the user to save the file to a new name, delete the original and then rename the document. Outlook freezing whilst it checks for mail and synchs folders. I think this one may be Outlook, but didn't seem to happen as often prior to W7. All these issues are intermittent, and did not happen prior to W7. I'm happy to work through them, but as I said - I wouldn't deploy firmwide becuase of these. Can't imagine the headaches my 'very non-technical' users would cause me as a result. Oh - all this on a Dell Lattitude laptop less than 12 months old so more than meets required spec. I"m sure fixes will come...
