Wonderful guys - looks like bootcamp's a no go since I don't have enough free space and virtualization may be too big of a penalty. I may just get a dell refurb i3 / i5 and a a/b switcher, since it's for work it'll be worth the minor investment.
As for specific apps, I"m mostly speaking in hypotheticals since I"m still interviewing. I just know I'd like to work a job with lots of remote working, and macs have historically given me weird problems from microsoft's remote access app freaking out to vpn handshake issues (and troubleshooting advice often written for older versions of OS X, which is annoying).
Since this is the os forum - I can google this but I'll ask, is it simple to get win 7 on EFI systems? I heard there are issues but I haven't really got my hands dirty with a pc hardware in a while. I hate windows 10, not because of it's interface but because I keep on trouble shooting family member's freezing/slowdown issues due to weird tasks eating up cpu and hd utilization, it's happened too often to be isolated events.
