Anybody home?

I wonder about the inactivity on RinkWorks. The last time anybody besides me posted was on Sunday.

So here is a question for my Wednesday post:

If I was going out to buy a "memory stick" and a usb minimouse, where would I be likely to find these items? If they come in different models, what features should I look for? What is the price range for these items?

I know what I said, but sometimes "a question" has several different parts.

Any input will be appreciated.
