Calculators you regret buying?

[Dave Britten]

I think "regret" might be too strong a word here, but I was never especially enamored with the Prime. I wouldn't go so far as to say I wish I hadn't bought it, but I probably wouldn't miss it.

I might go as far as to use the word "regret" with the SwissMicros DM41X. It's a wonderful idea, but the keyboard isn't great, there's no two-key rollover like the original, and it's been 3 years since any firmware updates, with lingering bugs and missing features. I am accordingly holding off on any DM32 purchases as of yet.
