What advice do you have in buying a computer and printer?

Episode 984
LaVerne fromLaVerne is ready to buy a new computer and printer and would like to know what Leo recommends. Leo says that if Laverne wants a laptop, then she should wait a few months until the new Haswell processors come out. Battery life will be doubled once that happens. She'll want to look for a 4th generation, Intel processor.
On desktops, there's really no need to wait and he recommends an i5 processor for most people. 4GB of RAM is the minimum, but no more than 8GB is really needed.
