I agree that carrying only one laptop has advantages but circumstances do not comply. I prefer to not use Apple products but own and use them anyway because my work requires using particular software only available on that OS. The *value* provided by the software/computer combination outweighs the inconvenience.
You are right. A personal computer may not always be linked and engaged to your RF workspace.
Either way on site surveys manly abroad one that does it all would suffice and be convenient. It's just a shame that you can run pretty much everything RF related in Parallels (Motorola CPS, IAS, RF Explorer, Nano VNA, all IC tools) with the exception of SH running Spike.
But as the song says: you can't always get what you want
