Adobe Acrobat Reader — the most-known software for reading PDF files — used to be good. But now it’s filled with bloat, and hogs memory and takes forever to load.
Don’t despair. There’s Foxit Reader, a freeware (the addons cost money, but aren’t required) PDF reader. It’s quick (takes a full two seconds to load a PDF on my computer — a little longer for big ones) and slim. And unlike Adobe Reader, taking up 20 megabytes of space, it’s incredibly small.
Go on, give it a try — and if you have reviews (or other suggestions for PDF readers) give it a comment.
