Hi aberg83, and welcome to the Forum!
I was not too familiar with the HP Mini 210 until you mentioned it, but having done a quick bit of 'googling' it does look like a very attractive netbook indeed.
I am not sure whether or not Bluetooth is an option, which may or may not matter to you, and of course the importance of OS X compatibility is something only you can decide really.
It may in fact be possible to 'hackintosh' this particular model in due course, and I am sure that some of our members who have experience in this area will be able to comment further.
Personally, I hadn't even thought about a 'Mini Mac' until I purchased my 10v, but having done so, I am very pleased that I did!
Good Luck with whatever you choose anyway!
