Parallels method: Expensive (200$ if you don't want to use cracks and such), takes a long time (~5GB to download + Windows to install) and use a lot of ressources (at least 2GB of RAM + CPU use)
Reliable torrents are very easy to find, and Windows 10 is free for anyone that joined the Insider program. Also, most (current) Macs have the resources necessary to run Parallels. Mine has 16 GB of RAM with a 1 TB SSD and an i7 running at 3.4 gHz. I also have a 60 Mbps line, so 5 GB takes about 20 minutes to download. Parallels also provides convenience for running other Windows software as well, so...I dunno. WINE is just a very dirty way of running stuff, and if I don't have to use it, I won't.
I don't like Parallels because it charge you and its not necessarily. It should be free like Wine.
Lolwut? Aren't you entitled.
