Well hold on there. Ubuntu doesn't actually do any support for "hardware" at all. If you have an Nvidia or ATI video card you get extremely shatty 3D unless you get their respective closed source drivers.
That is no different at all between MeeGo on the N900 requiring certain closed source drivers for the components.
Granted, this hasn't happened yet and is wishful thinking at current time, but it's at least at the same playing field as ATI contributing code to the the open source drivers while still maintaining their closed source counterpart.
Also, I was running pieces of 2.0 on my G1 long before the first 2.0 device hit market.. You don't need to wait for anybody..
Ubuntu has had multiple releases, MeeGo not yet one.
That entirely depends on your definition of "one-for-one". Remember, most things on the N900 are third party. As long as MeeGo provides us a working, functioning, user interface with some basic utilities such as a launcher and a way to add applications via a manager - everything else comes in the form of a third-party software release.
But again.. Ubuntu itself I don't believe really supports people (is there an "Ubuntu" phone number where you get 24 hour support for whatever system you're running?
Piecing together a Laptop is not easy.
Just because my computer doesn't support the newest printer that just got released, or the latest hardware from a vendor because they don't yet have a Linux driver - doesn't make my computer any less of a computer either.
I, for one, think Moobs are awesome!!! (wait.. did I just put that in public? ****..)
