My comment is bound to be redundant in this thread, but so have I. SumatraPDF is an excellent piece of software that has made life for countless people easier and without them having to pay anything in exchange.

It's as simple as it gets (with a UI), it's fast, robust and reliable. I wish governments would set aside some generous budgets for this type of projects that are consistently useful and reliable, like they do for arts and education (well, some governments).
