I'm thinking about getting Ubuntu 64bit, 'cause I just saw that my PC supports 64bit. Now, I already have installed Ubuntu 32bit, is there any way to just change it to 64 bit without having to remove it first?
And if I have to remove it, how do I do that? I have partioned(?) my HDD, if that plays any role :P
Oh, and one last thing... I stumbled on a thread saying something about programming in 64 bit is harder or something... So, is it massive headache to program in 64 bit?
Thanks in advance.
