Acorn Atom - more ebay craziness

http://search.ebay.com/251105620795 Hardly Apple I territory, but 1,100.00 GBP (~ 1700 USD) is an incredible amount for a home computer which occupied the middle ground: not as ubiquitous or famous as the Spectrum, C64, BBC micro etc., but not as rare or desirable as those which came before it (ZX80, Acorn System 1 etc.) It's not as though it's an early release or one of the ones sold in kit form. The lack of serial number on the case raises the possibility that the case and PCB weren't paired at the factory (which surely makes it non-original and a mongrel :-) I can't even begin to make sense of most ebay sales, but what do people think? Just someone with rather deep pockets? Or perhaps the seller buying it back themselves in order to create an inflated sense of 'market value' (and with the intention of re-listing it under a different account in a few months)? cheers Jules
