Not really. Although increasing in number, press-fits still comprise only a small proportion of the frames out there. And while all formats have their possible problems, I haven't found a noticeably higher proportion amongst press-fits compared to screw-in. I've only come across one frame where the fit is a little bit looser than ideal, and it belongs to a regular customer, so I'm keeping tabs on it when it comes in for its regular services.
Just ride the bloody thing and enjoy yourself!
