I post my resume on job boards and I can't tell you how many ****ing cretins from back East think it is OK to call me at 5:57 A.M. Pacific time. The service lets me forward calls received during off hours to voice mail (with a greeting that tells callers to please call back during regular business hours Pacific time).
Not only that, if I have a need for a number in a different area code, or a toll free number, I can easily add it to the system.
But that doesn't include a number in a different area code, or a toll free number, you can easily add to the system to forward to your mailbox, though.
You can cut a pineapple with a knife in the same amount if not quicker and it's not that hard, I actually think the corkscrew method is more difficult as you still have cut up the pieces after you remove them, where as with a knife you just cut them as you desire to begin with.
I can cut my own diced exactly how I want it in the about a minute. For example, this guy is not the best as he is a bit of a clutz but should give you a general idea (I also don't know why he saves the core as I just throw it away) but just for example:
I think a good knife that you can do anything with is a better cheap luxury than a pineapple corkscrew, and with a little practice you will be more efficient with the knife than the corkscrew too, also I'd rather not have the corkscrew as one additional thing to clean afterwards.
All that being said, if you like the pineapple corkscrew method I can't blame you, that's quick and easy too and produces basically the same results. The luxury for me is I have one less thing to keep track of and have to clean and also think I'm more efficient with just the knife.
