I prefer to use Ubuntu.  I'm looking for a laptop with touchscreen that 
can work as a tablet -- either detachable or 2-in-1 (flippable).  I'm 
hoping something out there will work well with Linux.  Right now I have my 
eye on this one:

Any ideas?  I have to say that Ubuntu "works closely" with HP and 
maintains a list, and that machine isn't on the list...

That seems like a bad sign.
