i got both mine 2nd hand off a classified forum, not here
but got real bargains on both.
you can't actually run OS X on any pc but a mac, but you can run windows on a mac
once you have used a mac you won't want to go back
have you thought about trying linux on your windows pc
why buy an over priced mac when the hardware is exactly the same as a lower spec windows laptop
there are a few dells that will run osx and i have a dell mini 10 running osx and my desktop is duel boot windows and osx
as for osx being better its each to there own and mine is rarely booted to osx
As above the general rule of thumb is as long as you have Intel and your computer is basically post 2010..also depends on your graphics card as some are not supported by lion so just see what your computer has and go from there..as I said basically any desktop or laptop post 2010 will run Mac OS.
As it goes im doing exactly this this evening..going to try and install mavericks mac os on my compaq laptop,once i have downloaded the 12gb files required.....fingers crossed..
