Got my full license early 2008 and still not worked 100 countries (confirmed). You could say I had a lot of off-air time. But since 2013 I participate in more then a few contests and my first DXCC-award (mixed) is appearing on the horizon. I do have a shoe box full of QSL-cards and mixed with my Logbook of The World confirms I do have 100 countries confirmed. I did look in to the process of having my cards checked and apply them for the award but I decided that’s too much hassle. In LoTW I have 96 confirmed countries, so four more and I can apply for DXCC mixed without even opening my QSL shoe box.
Sounds nice to me! Don get me wrong, I do like to receive paper QSL’s, especially from special stations or very remote locations. But for award checking it is far more convenient to have digitally confirmations.
