In reply to KeithWakeley:
Hi keith, thanks for the detailed response. From a very quick glance, the Paperspace facility looks similar to something we sometimes use at work for cloud rendering (I think - I'm no expert!) The demo video on its functionality was a bit over my head, if I'm honest!
I don't use SketchUp very often, even at work (where we also use Revit, mostly on monster jobs). I just need it at present to get some 3D views of my small house extension and I thought it would be a good opportunity to have a more detailed tinker with the programme than I've done to date. Working early mornings and lunchtimes in the office is fine, but I'd like the option to use SUp at home in the evenings.
My wife's also reminded me I had another spare old desktop at home which used to have both SketchUp and Microstation on it, so I'll check and see if that's still running before I look further afield.
Thanks though for your suggestions and info on Paperspace & laptops.
