... and while there are *some* advantages to running a 64-bit system
there are also downsides still.
Advantages (that I can remember):-
You can use huge amounts of memory efficiently (i.e. if you have
more than 4Gb or memory)
Some other things may run more efficiently
Disadvantages
There may not be all the drivers you need available in 64-bit
(maybe less of an issue nowadays).
There are likely to be more little niggles in the installation
process to overcome as 64-bit simply hasn't been around so long.
If you *need* to use lots of memory then go for 64-bit, otherwise I'd
stay with 32-bit.
