This is not the first time I’m saying that Adobe Reader is very slow. PDF documents are commonly opened by Adobe Reader, the most popular PDF Reader right now, but it takes time to startup and is very slow.
I’ve always looked for the best and fastest applications I use for whatever work. And in case of PDF readers, I mostly prefer webapps for handling such documents like .DOC, .PPT etc. But for people looking for a simple desktop PDF reader, I’ve found a great app!
