I absolutely agree but I think you overstate the computing power of the N900 (just like the superphone hype over the Nexus). For casual browsing the N900 shines. For computing work, I'd still rather have a pocketable computer. Since the debut of the Intel Atom, there have been more and more of these announced (literally every day at the moment since it's CES time). They don't need EasyDebian or WinMo, they run Debian and Windows. Plus the screens are bigger so old people like myself can actually read a document in OpenOffice. Someday there may be a true converged device. For now, it doesn't exist. The N900 is a more capable phone with data capabilities than most but whether you call it a smartphone, superphone, Internet phone, or whatever, to my mind it still needs to function first and foremost as a phone.
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
