When this PC I am using was being built the toughest decision was which OS to use....I must admit that I was a bit worried about choosing the 64 bit Vista. December last year I knew very little about 64 bit and spent a lot of time reading horror story after horror story about Vista let alone potential issues with 64 bit. The Vista articles I read I noticed were pretty old.
I felt happy that all new drivers for Vista must also be written for 64 bit....so I was told.
I think it won;t be long before 64 bit software is in the majority. I'm very happy with my 64 bit OS and really haven;t had any problems driver wise.
I'm just ready for the future!
