OHHH ba humbug Yaw bunch o scrooges!!
If your getting a laptop it will have all the drivers you need for the machine installed. Any addon equipment after that, just check before you buy. Most things will work if they are new. The 64 bit OS (Windoz) I'm assuming will emulate the 32 bit system to run your 32 bit software.
Just know that 32 software runs with 32 bit access, so it will not run as fast as the same 64 bit software. So you will see some better performance overall but not everything. Software companies are being slow to move up, but more are coming along all the time. You aren't going to have all the problems everyone likes to lay claim to. I've been running on it for a long time now. Nothing I've wanted to do yet that I can't.
