This. I spent some time learning Solidworks, drew up some cool stuff, and suddenly my files were worthless. Sure, they'd load in other tools, but they couldn't be edited. Eventually bought another product, but it worked enough differently that I really didn't want to face the learning curve again.
I finally got the veteran deal for SW, so I've got it again, but still have a bad taste in my mouth. Been off SW long enough that I feel I'd have to re-learn it all. Haven't felt too enthusiastic about that. I think they're less likely to pull the rug out from under veterans, but just can't get fired up about using it.
