Turn Your Entire Office Into a Whiteboard

Whereas tileboard is $12 for a 32sf chunk. So cheap that even if it does break down, it's still cheaper to replace it a dozen times rather than put up IdeaPaint.
Rustoleum makes a whiteboard paint that seems cheap, but you've actually got to layer it many times to get decent performance. And even then it's not that great.
We're going with the tileboard route at the coworking place I'm putting together here in Atlanta. Shameless plug: http://www.ignitionalley.com
The reality is though, the more space I used to have whiteboard discussions with others, the harder it was to capture this information for later use. Nearly all of the time, a pad of paper or a smaller whiteboard was suitable for the conversation.
My ex officemate (university offices, paint wasn't an option) ordered a ton of magic whiteboard sheets and got the same effect - very impressive. The only problem is knowing where the whiteboard stops. (He didn't.)
Ummmm...
Do a quick search of dry erase paint. Rust-Oleum makes one for about $20 for 50 SQFT.

Also leaving a visual trail of the development of your thoughts make it easier for others (and you) to follow and gives you something to refer back, rather than trying to remember a long chain of complicated arguments.
Personally I like using a whiteboard even when just reasoning out things for myself.
Pretty damn nice.
