I believe ARM takes care of many of issues discussed in this thread.

The ARM core itself has nothing to do with it - you still need to provide all the hardware and software to create a USB host, and to implement the necessary filesystem to access the actual information on the pen drive.

On an 8051 type MCU I find that file system code could take about 20K of instruction space...

20K out of an 8051's 64K maximum is a big deal; an ARM will probably require at least that much code - it's just that even 64K is not necessarily a big deal to an ARM!

But then this means switching to new platform

Yes - it's always hard to decide whether it'll be easiest in the long run to struggle on with the architecture you know (8051), or dive into an unfamiliar architecture, but one that it (probably) better suited to the task (ARM)...
