When you update your iPhone, you can't "unupdate" it, Apple after a while always deletes the certificate of all versions that aren't the current, and the installer always check the certificate before installing (this also means you cannot install iOS without internet). I don't recall if the machine was actually built (maybe it was the Digital Orrery?), but I do recall one of the contrary viewpoints being that VM was considered important not just for simulating a larger memory system, but that for type-driven hardware like Lisp Machines, a huge address space was useful because the upper addressing bits could be used to encode type, even if that address space was too large to ever be populated.I work with mobile dev (among other things). Hal Abelson and Gerry Sussman were behind these big ideas (the same duo who wrote Structure and Interpretation of Computer Programs). By today's standards, that's pathetic, but recall that this is in the era where PCs had 640 KB, max, and 1 GB was not only larger than every hard disk (desktop ones were at 10 MB, and even the big enterprise drives were only on order of 10 times bigger), but - and this was the really important part - would fill out the virtual address space, so there would be no need for a VM system.
A machine was designed with 1 GB of main memory. There was a project at MIT LCS/AI back in the mid-80s to explore what it would mean to have massive amounts of RAM. It should have worked since it's not really any different from compiling programs for memory-resident operation.)
(Did anyone with a battery backed SRAM PCMCIA-card try eXecute In Place on the Amiga? I would like to know if it actually worked or if it was just a term mentioned in the manuals. This makes it hard to transition into XIP-system where loading is something that doesn't happen. (Like XML or other text based configuration files.) A lot of programs are also using datafiles in an abstract format that require extensive parsing before usage.

The problem is that both Windows and Linux is badly prepared for this since both of them uses executable program structures that require modification upon loading.
Everything will be memory mapped always like it was in the good old ROM-based days. The real change we will see is when memristors replace flash and dram since there will no longer make sense to keep the bulk storage in a different memory from the rest of the system. Memristors will make a dent in the small scale UPS market since there will be no need to shut down gracefully but we will still need large scale backup system where you want to continue running your operation during power outage. (In practice that is, in theory it should all work.)

I have yet to encounter a Windows or Linux system that you can upgrade without rebooting. Ofcourse we will not see the end of the reboot entirely.
