Frank,
it is quite simple really.
what you are experincing is what everyone else is more or less experiencing.
Despite 64bit having been around for a few years now, we are still in a transition period if you like.
However, we are getting closer and closer to the cut off point where 64 bit is 100% the norm and software developpers will not bother with dedicated 32 bit versions.
So, the ONLY logical move, if you want to think a little bit more "long term" than the next few month, is to go 64 bit.
Most 32bit plugin still work well in 64 bit enviroment (especially with Jbridge installed), and yes, a few of them worn't work so well, or not at all.
The major software developpers are updating their flagship plugins to be 64bit and soon enough this will just be the norm.
So, if you are reverting to 32 bit now, what you are in effect cutting yourself from is all the new plugins that will be 64bit only.
Therefore, there is no need to be angry about "the hype of 64 bit" etc.
It is just an evolution in computing technology like there's been many before and there will be many to come.
Make sure you check all your plugins are up to latest version etc.
All the best.
