Who needs 64 bits?
who needs them? people who runs 3D raytracing renderer for animated feature film? physics simulation? GIS? i'm not a scientist (you claim to be one) but i do highend 3D rendering. and obviously i'm more technically advanced than you.
Really! there will barely be any noticeable difference in performance, I run x64 and still I am running applications for 32b without problems,
applications that doesn't need lots of RAM won't notice the difference, yes.
yes you need 32 bit libraries, so what? good deal, just add 2 more Mbs to your disk drive, stop being stubborn about 64 bits, the performance difference between both arch is barely noticeable except for especialized applications and runtimes that can take real advantage of it.
with the risk of bricking your system because of polluted libraries? a week ago i failed to install a license server for a well-known 3D application because of mixed libraries between 32 & 64.
Skype would also have to double support and the development/maintenance cost of Linux Skype would increase.
oh really, simply replacing some 32 bit pointers and data and recompile for 64 bit will _double_ the development cost?
btw, I am a scientist too and it is a shame that a fellow scientist cant understand about pragmatism.
a moron like you and you call yourself a scientist? what a joke. get a clue before opening your mouth. stay away from linux cause you WILL brick your system.
