I got into Costco today, and much to my surprise, they had an employee monitoring the computer & jewelry areas, and she was quite well versed.

The model on sale doesn't have a separate numeric keypad, and I think it's almost a pound heavier, so I purchased this one online... she actually found it for me

Now, knowing that I'm working with a minimum 7 year old desktop, and have a backup drive, mouse, keyboard, plus a thumb drive for duplicate backups of quicken (yes, I'm paranoid), what accessories to you think I need to be able to swap out to the laptop? While I'm still in NJ, I'd like to continue to use my monitor if I can.

And millions of thanks for all you help/adivce.
