I don't use them at all. I run Linux on my home computers, so no silverlight. I also like to houserule and/or use homebrew or 3pp material.
Making a character without the tools is really easy. I can fit a whole character on half a page, and the longest things are choosing a feat and purchasing equipment. Everything else is done in 10 minutes. I do use the compendium a lot for this, but that's just an expedient for finding every official option fast, instead of flipping through all of my books.
Since I'm so much more familiar with the rules than my players, we usually create characters together, them telling me what they want, and me finding and suggesting options for them. Afterwards I type up the character in a monster-like stat block, though we could just run with the half sheet and reference the books if we really wanted to play right now. It works really well.
I do use computers during play (a combat tracker, and the compendium), but those are luxuries I could live without, if needed.
The game is perfectly able to be run straight out of the books, if that's what you want to do. If you do, I do suggest limiting options, though - Essentials only, or Player's Handbooks and associated power books, or something like that. That'd make it easier to find things quickly.
