Reading the latest DJTT blog post, I noticed the claim "There is no RAM."
Just wanted to point out (as an iPhone and soon iPad developer) that iPhone-like devices (iPhone, iPod Touch, iPad) definitely do have RAM. Apple does not advertise that fact, because it does not deem it important. (They don't advertise processor speed either for the iPhone and iPod Touch.)
The iPhone 3GS has 256MB of RAM, while the earlier iPhones and all the iPod touches all had 128MB of RAM. I won't know for sure until I get my hands on one (unfortunately even developers can't get 'em early), but I imagine it'll come with either 512MB or 1024MB of RAM.
More importantly than the size of the RAM though, is the fact there *is* RAM. The suggestion that it uses the main flash memory as a "scratch / swap drive" is false. If it were true, it'd be really bad for performance, but thankfully, that is not the case.
