Neither the press release nor the company's news blog revealed the identity of the critical component, so I reached out to my PR contact at Samsung while he was mostly unavailable at CTIA last week. I heard back from him today and unfortunately, the news won't make Steve of UMPCPortal happy at all.
According to the email I received this morning, the CPU inside the Samsung Mondi is the 800MHz S3C6410 ARM11 Mobile Processor. Sorry, folks, no Cortex in this one. I hope the price is a reflection of that.
