I use clicktoflash for Safari, and I'm extremely aware of the use of Flash on the internet. I just don't care for most of the content that is distributed using it, and also don't care for the experience of it either.
I consider that owning an iPad that is Flash free will bolster the numbers of non Flash users seen in website statistics and will help to contribute to its eventual demise.
I'm also totally serious about buying an iPad, and will almost certainly get one refurb.
Edit: Believe it or not, I became more aware of how prevalent Flash is after I started using clicktoflash.
Good for you! (Seriously) You will be an informed buyer.
It is not that I am a fan of Flash, because I am not, but because I am unable to access far too many websites without it. If Flash were to go "poof" and disappear tomorrow I would not be in the slightest bit upset. In a few days the websites would be doing something different and we could all get on to the content we are after without dealing with this problem.
Unfortunately, Flash will not go away because of Steve, Apple or the iPad. The only way Steve can rid the 'net of Flash is to buy Adobe and slay the "dragon up close and personal". He would enjoy that!
