And I recently replaced my piece of crap one that came courtesy of Harrahs with a nice, aesthetically pleasing but very functional one and I use it all the time. The piece of crap one though was so bad that manual was better.
I wouldn't say that I'm anti-electric or anti-automatic, but I find the design of the can opener I use to be vastly superior to the design of the standard electric can opener. (And most manual can openers.)
With my RSI and Kristin's problems with her elbows and the resulting trouble we were having opening stuff I finally convinced us both that it was stupid not to get one, even though it does seem silly (because, as you note to Sabyl, we really don't open more than a few cans a month).
I hardly ever cook (see above) but to the extent I eat soup (infrequently) it's stuff like Progresso that I got in 8-packs from Costco, and they all have pull-tabs these days. There are also like brick packs from TJs with tab-y things. Is Campbells or whoever still using regular can tops?
I grew up with an electric can opener in every house I lived in or visited, and using them was an everyday sort of thing, but I kind of forgot about them after I left my childhood home and started building my own household. I was thinking about them just a couple weeks ago, and marveling at the fact that anyone would ever use one. (The thought was inspired by a similar thought about popcorn poppers, though at least those have some sort of lame-ass health justification for some people.)
I remember having one in one or more households growing up. I know I had one for a while when I was married to D - more because someone gave it to us as a wedding present than because we actually wanted it. I've had a manual opener at least since moving into my previous house, about 12 years ago, possibly before that. But once a year, I really wish I had an electric opener - when we do the 50+ person chili party. I open upwards of 30 cans (tomato sauce, tinned chiles & mole, beans, clams for dip, that sort of stuff). I suppose I could borrow one, but I never seem to think of it.
