architecture

I have a Core i7 laptop with 4gb ram. In windows, the disadvantage of using the 32bit OS would be that a single app could not use more than 2gb of ram (+ the 2gb shared kernel-space memory) except when setting a boot switch which reduces the amount of shared kernel memory, then it's 3GB max per app.

What disadvantages/limitations would I have in Ubuntu for sticking to the 32bit OS? (If any?) - As I only have 4GB of ram, I can't see why I need to use the 64bit version?

Windows 7 on a 64-bit computer

I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
