Reasons for Vista

[Geoff]

If one has 64-bit hardware and running 64-bit Vista, why do apps have to be
64-bits?

I know vista can run 32-bit apps but are software makers compelled to move
their app to 64-bits? For example, take Cisco or AT&T dialer, there is no
way they would use 2 to the 64th power memory because they do not even use 2
to the 32nd power memory.

So, does that mean many apps will remain 32-bit apps for a long time?

Thanks.

For many types of software, there is no compelling reason to move to a
64-bit architecture. Part of it is hype--an attempt to make people
buy new hardware that they don't need.
