Umm 64bit because I would like to use all the ram in my laptop. I only run 64 bit os as all my chips are. why run a slower version of vista/7/linux
I don't get it. I suppose you can use a 32-bit system to address up to 4 GB of RAM (which is your situation I suppose).
Besides you're not really forced to 64-bit linux anyway. In my work, I got a machine that has 16 GB of RAM. And I have Kubuntu 9.10 installed, 32-bit version as well. There's a hack (not sure, in GRUB2 maybe) that allows 32-bit linux to be installed on a machine having more that 4 GB RAM. And of course, my Linux sees all 16 GB of RAM :lol:
So to me, installing 64-bit linux nowadays is as someone said, more headaches (to already a lot caused by Linux programs / libraries (well, unless someone is using Linux to be fixing all the stuff all over)).
Think over pal.
