Hi Ben,

I've just had this situation and decided to go with 64 bit.

For the Flash concern this link:

http://ubuntuforums.org/showthread.php?p=1174435

shows how to add a 32 bit version of Firefox (you'll end up with both)
and it worked fine for me (you get the new version of Flash). It has
automated scripts for Dapper and Edgy. I used the manual instructions as
I am using Feisty. I know there's alot of opinion as to whether the
64bit is worth the trouble and there is much information on the Forums
(Wine is perhaps a particular problem but I don't use it so didn't
investigate that) but I am glad I took the plunge.

cheers,
bob
