I am curious why so many people want to jump on the band wagon and get Vista and also curious as to why people want to use 64 bit systems. What real advantage is there? Is there any understanding of 32 bit vs 64 bit and what companies who supply software have to do to supply software for 64 bit systems? I cannot say I understand all there is to know about O/S's and 32 bit or 64 bit storage systems but I do know it is a hassle to create software that will work on systems with different requirements such as 32 or 64 bits. It requires a compiler that has the capability to compile the code for various bit sizes then you have to take the sorce code for a program such as Anydvd and compile it for the OS/bit size in question.
