Just wanted to let other know some info in case they have a similar machine or are considering getting one:
I use HP among other tuning software on both my Mac Book Pro 17 and now on my Mac Book Air 13. I did partion my drives so I can run a "real" install of Windows (then use a free boot menu called refit to choose what I want at boot up).
I put Windows 7 32 bit on my pro before I had a copy of 64 bit. I installed 64bit 7 pro on my new Air and HP tuners works good using the special Vista HP tuner drivers.
I have not personally tried HP via parallels or any of the other Windows emulator type software...
This may already be known info, if so, sorry for the repost... just thought I'd share that HP works on a lot of Mac hardware
