I think the new mate interface alone...

... is worth the upgrade to 2010.

I have always found the mating interface in SW to be a real pain. Disliked it way back when. Hated coming back to it in 2009 after using ProE for 3 years.

Much better now*. Thank you.

* Still like the PTC way better....but I'll give you guys until SW2012 to really fix it. :-)
