* First disadvantage is that even now not many programs come in 64-bit. A good example is that there is no 64-bit media player. So eventhough it you can still use 32-bit players, you are essentially wasting the additional processing power by not using it. PS doesn't have 64-bit version either.

* 64-bit machines draw more power and heat up more due to the same.

* 64 bit drivers are still a big issue.

* Many devices are incompatible with 64-bit OS (apparently even after installing drivers, though this is rare.)

* Some language compilers are reported to have issues in a 64-bit environment.

* Not many games use 64-bit capabilities.

* although most 64-bit OS support 32-bit applications, some 32-bit applications do not support 64-bit OS.

These are some thta I remember from top of the head... google for a far indepth knowledge.

But do not let that put you off. The simple matter is that since 64-bit is becoming more popular, many application exclusively for 64-bit have been written. Most worthwhile 32-bit applications will work on 64 bit. If they do not, it simply means that they have a 64-bit version.

The advantages of 64-bit outweigh its disadvantage. In case of Vista, the biggest and the most prominent advantage is that only the 64-Bit Vista supports more than 4GB RAM.

Ah, thank you. As it is now it looks like the only computer I'm using 64 bit is on my home computer power house. My laptop's battery is as bad enough as it is. Two questions: is the amount of energy drawn very significant, and do the devices include, I don't know, things like iPod synchonization?
