I'm trying to keep my receipts and other important documents in digital form (as searchable PDFs). For many years I've been using an old copy of Acrobat CS2 which came with my iMac many moons ago and right now this is the only reason why I have this clunker around.
I'm curious what other people are using these days to (hopefully easily) convert paper into searchable PDFs. Spending several hundred dollars on an Acrobat upgrade (or committing to a monthly tithe via a subscription) doesn't get me super-excited.
