The upgrade to Professional means that you can use the old things through WIndows XP-mode. Or something. I'm not very clear on this, nor am I very computer literate.

And yeah, I know about the difficulty of replacing or adding stuff. The machine we're currently using is so old that even the adapters to replace things are few and far between. Granted, this is a dinosaur at about 10 years of age. The reason we aren't getting new parts for our newer computer shell (it's only four or five years old)is because it's cheaper to get a whole new computer. :-P

All part and parcel of our disposable lifestyle we Americans coveted for so long.
