I am thinking of buying a new laptop.
I am totally ignorant abt 64bit - why should I go 64 - what's the advantage - is it the future? I mean will we all be using 64bit computers a few years from now and only 64bit software ?
anybody willing to enlighten me or point me to a link?

I think the 8GB of memory cap is a huge benefit. My machine runs so smooth even multiple virtual machines are running.

Yes being able to use more memory in the future is a big plus
A minus I came across from this link

is
If You have legacy devices like scanners and printers that do not have 64-bit device drivers. 32-bit drivers are not supported under 64-bit Windows 7, so you should make sure all the devices you need to use are compatible with 64-bit.

Everything will work okay. If you have more RAM than the 32 bit OS can handle (4GB?) you'd be much better off with 64 bit.

As a rule of thumb: Choose 64 bit whenever you can, and 32 bit when you must. When it comes to AutoHotkey scripts, I develop them using AutoHotkey_L 32 bit version, for compatibility reasons (I want others to be able to use the scripts). Optimal developers should distribute both 64 bit (for speed) and 32 bit versions (for compatibility reasons) of each piece of software.

Total address space is limited to 4GB (2**32 bytes), but some of that is reserved for other devices and purposes. The actual limit on RAM varies, but it's usually between 3 and 3.5 GB. There are some programs which can utilize the extra RAM - e.g. for RAM drives.

If you have hardware (esp. peripherals like printers) which is more than a couple years old, driver availability for 64-bit can be a problem, though perhaps not frequently. Software compatibility problems aren't unheard of either, especially for businesses which are stuck with old software.

suppose 64bit windows, using 32bit ahk

what is the advantage to moving to 64bit ahk? sumon says speed? but most ahk scripts aren't gonna be very cpu intensive to begin with... i would think the hassle of updating scripts for pointersize isnt worth it
