Good point.

So by the time we are capable of doing this, all the hospitals will be 
doing it anyway?

There would doubtless be some kind of cost-benefit calculation involved, 
to decide just who would get this treatment. Unless you're in America, 
where, i assume, you die if you can't afford whatever life-saving 
treatment you need (is this correct?).

A problem i can see here is the usual assumption in the medical 
profession that there is a point at which you should be allowed to die. 
Once you've had a good innings in conventional terms, there would likely 
be little incentive to make great efforts to keep you alive. Perhaps it 
would be a good idea to try to promote the creation of 
'transhumanist-friendly' medical clinics. Probably a bit too much to 
hope for.

Actually, one good reason for removing the brain from a failing body 
would be for ease of access to all the life-support systems, and ease of 
swapping them out for others as and when necessary. The 'body' would be 
whatever physical infrastructure the life-support modules were plugged 
in to, and you could then take advantage of heterostasis, keeping local 
conditions optimal for each system separately, without upsetting the 
rest of the body.

It would also make cryonic suspension much easier if that was eventually 
decided upon. Plus easier other things, too, like neural interfacing and 
  eventual uploading.
