A surface pro is a pretty nice adjustment if you are used to the finish level of an apple product.
You need to be somewhat savvy to use VMWare, Parallels, or BootCamp to run Windows 10. However, there is lots of how-to guides out there. I agree it’s kind of silly to buy brand new hardware if you already own something semi-current.
There are actually 2 (or kind of 3) ways to run Windows OS on modern Apple hardware:
#1 You can run Parallels, or VMware to run the Windows OS as a virtualized window inside of the running Mac OS - This has some benefits, and some limitations - 3D acceleration, for example is lacking.
#2 You can boot into Windows OS directly (using Boot Camp) - This works extremely well, but at that point, you are running Windows, or Mac, and you need to reboot to switch between the two. This is the solution that should work well for you.
#3 (kind of) ia to set up the system to tun as in #2, but then open that Boot Camp partition using parallels (as a window running under Mac OS. That method allows for some of the benefits of a virtualized OS, but not all of the benefits - you do not get the full 3D acceleration speed.
Still, #2, and #3 do not require you to set up the system differently... you just choose which way you want to run it, when you run it - If you want the full hardware support, boot into windows. If you don’t need the additional support at any given time, you may simply choose to open that boot camp partition with Parallels, and then you have the windows OS in a Mac window, so you can work within both environments simultaneously. Then when you want to have the full hardware support, you reboot into the Windows exclusive mode.
So, in other words....
Set up for Boot Camp, and you are good to go.
Then, if you want to run Mac and Windows simultaneously, you can add parallels, and use it to open the existing Boot Camp partition, allowing for 2 simultaneous Os’s, but you do loose a little hardware speed if you choose to operate in that way.
Surface Pro or Surface book are great choices, well made with quality similar to the Mac products. You can also get one used on Ebay for a good price including add-ons if the expense is too high for a new one.
