Bod:

I'm not a Raspberry Pi guy (yet), but I'd expect it to work like a typical 32-bit x86 installation; meaning that while a single process is limited to 4GB, the OS can have multiple processes running to use the entire 8GB address space of the CPU. So you won't be wasting the capabilities of your 8GB RPi unless you're running just a couple of processes.

...roboticus

When your only tool is a hammer, all problems look like your thumb.

    You are correct...

    I skim read this article a few weeks back and it was only then that I realised the limitation of 4Gb RAM on a 32 bit. What I didn't properly read was:

    "The 32-bit kernel is joined by a 32-bit userspace, however: While the kernel can see and use all 8GB, any given process on the system is limited to 4GB. In other words: If youíre running a single application which doesnít fork into multiple processes, itíll only ever be able to grow to half the 8GB available"

    We 'attend' several virtual conferences and training session which are full day or multiple day events. So we take part using the big television in the sitting room. I plan to get a Raspberry Pi as streaming device for these events and it will largely just run one instance of one browser with one tab open so, for this application, I might hit the limitation. But for general usage, like the OP is looking for, it is probably the ideal solution.
