Regardless, rjdohnert gave props to W8 and Metro; why would you think he was being disingenuous about the file copy? He's been a C9 member since 2004 and I haven't seen him flooding the forum with negativity about Microsoft. Why are you always so dismissive of any issue or complaint about Microsoft's technology?
Nevertheless, claiming that a network issue is prevalent to Windows 8 is specious at best. His complaint about the network issue was amid a list of things he hated about Windows 8--not Windows RT or the Surface specifically.
