It was that I needed any kind of a tool to open a jar - basically she thought I was a wuss because I couldn't manhandle a jar open barehanded - I was giving in to the "weak female" stereotype. ;-p pffft!
If you have hand strength or pain issues things like opening jars and using a can opener can really be a challenge, so electric versions definitely have their place. It took up counter space, but for me, at that time, it was either that, or wait for my husband to get home from work, or not use anything in jars. It really made a difference for me, and many meals would have been late or undone without that helper. Thankfully things have improved and I can use less space hogging options but back then I may have said that was my most useful gadget. :)
I use my bench scraper for leveling dry ingredients. Now, that's a useful multi-purpose gadget! It can clean up the counter after a dough session, cut dough, cut brownies in the pan, level, lift, scoop, trim, frost...
