It's not quite as you have described it. Yes, we want a 64-bit BIAB, but it's not always clear to everyone why.

A 32-bit app can only address 4 GB of RAM, true, and some of that (around a GB) is taken up by Windows leaving at best 3 or 3.2 GB free for programs. Yes, BIAB is a 32-bit program. No, it is not always limited to using the 3 GB RAM described, because of the JBridge utility. JBridge allows BIAB to use all of your added RAM if you are using a plugin. Plugins are the main reason people want a 64-bit program, but BIAB found a way around that.

All this assumes you are not limited by a 32-bit Windows anyway, but if you recently bought your desktop, it probably uses 64-bit Windows.
