Having your own printer is almost a must. I can't visualize being without one. Very reasonable cost nowadays.

I have a mobile hard drive with everything backed on it. I would recommend this as well.

The HP should do just fine. All of them can have problems, so have good coverage. And again, a separate hard drive, kept in a separate safe place when not in use, gives peace of mind.

Oh, yes, that little pad for many people is hard to use; get a good mouse (I like a wireless).
