Well stay away if you can... We are developing customer software where actually the customer gets all source code and a license for further developing on the project. Now, if MS only sells VS2010 we have no good argument to keep 2008 around, and we also do not want to explain to the customer that at the end of our development, we will upgrade the project from 2008 to 2010, making it essentially un-editable on our side. So the simple but effective deprecation of old versions leaves us no choice, and it´s the same with Win XP vs. Win 7, Server 2003 vs 2008 etc. We have sub-suppliers who still cannot confirm that their software will run smoothly on Win 7 / Server 2008, forcing us to make manual downgrades which are costly and leave much of the available power (64bit, huge memory) unused. On the other Hand, Windows 7 seems to be a big leap forward. It´s attitude towards the user is much more optimistic and the useability has really improved. Stay away from Office 2007 & 2010 dough :)
