And look in the crystal ball if that will change.
For instance, the web, word processing and even video editing will all still be quite nice on today's 32-bitters in 2 years.
However, the gamers will not be happy from what I've seen. The newest titles may be "best on 64-bit". Also, some video editing and database work is a step forward on 64-bitters.
99% of the people will feel little effect in 2 years. But I bet I'm wrong.
I just ordered a Toshiba notebook with an Intel Pentium M, but am having second thoughts based on some reading i've done regarding new 64 Bit programs. I don't want to buy a new machine only to find it uselesess or frustratingly incompatible a few years down the road because its processor is not 64 Bit compatible. Can anybody help with advice on how important a 64 Bit processor will be if I plan to keep my notebook for at least 3 or 4 years?
