I'd never go back to 2008. There's just so much more you can do with 2010.
Here's just a few:
Sheet Metal - Vastly Improved
Frame Generator - Now easy to add custom shapes.
Sketching - New Sketch tools and options. Silhouette Curve for parting
lines, etc.
Surfaces - Improved.
Translations - Both Improved and more Flexible with new translators.
Assemblies - Petter performance options, Patterns of Patterns, Shrinkwrap,
User defines folders, Assembly restructure inprovements.
BOM - Improvements
Content Center Improvements, Desktop Content for single users, Move Library
content, Family Table View, Edit family tambles in Excel.
Design Accelerator - Cylindrical Cams, Spur Gear improvements and others
Drawing Annotations - Spline dimensioning. User defined symbol folders,
Balloon snap and others
User Coordinate System (UCS), XYZ Axis labels Enhanced measure
If this is not enough, go to New Features Workshop in 2010 for much much
more.
Things to consider:
1. 2010 will not be productive with less that 2 GB RAM ( 2008 was not
either). If you are working with really complex parts (think engine block
castings, etc) or very large assemblies, then 64 bit with a minimum of 8 GB
is the only way to go.
2. Make sure that current graphics cards are up to the challenge of running
the ribbon. Update the drivers, etc.
3. Regarding License Manager: Create deployments for both Suite and Pro
versions. Install Suite for Suite only users. Dynamic licensing works like
this: If a user accesses a Pro feature, then he will "own" a Pro license
until he exits Inventor and goes back in. This is no different than previous
versions. Initially, all users start out in "Suite" mode until a Pro feature
is used.
4. Change is inevitable. If properly implemented and trained, IV2010 WILL
make you far more productive than 2008.
