First off, I'm mentioning this with no professional endorsement: purely a personal view here.
How many gifts given this year come in those form-fitting clear plastic packages? I know that one present Santa brought to our five-year-old -- a new ATM machine -- came in such. You know the type: no matter what you do, or what tool you use, you are bound to either a) cut the item or instructions securely bound in the package, b) injure yourself or others in the family to a degree requiring a holiday trip to the urgent care clinic for some holiday-coloured stitches, or c) return the product to the store without opening in quiet protest of such packaging.
I saw that Steve was worried about the same thing today, and thought that I would offer this inexpensive, innovative tip: get an OpenX. This is the best thing to hit since the Olfa touch knife I tried to master in my days doing graphic design oh so many years ago. This little device now saves me agonizing injuries (I still have one little scar on my wrist from a plastic shard that continues to give me the willies) and is easy enough to use.
There are packages that are a dream to open (as I wrote recently about my zune OOBE), and then there are packages that double as medieval torture devices.
IMHO, the OpenX is awesome.
