I had a series of HP devices around this time including an 11C, a pair of 48's, and a 200LX. The 200LX was the one that got the least use. It was would've been great if I had a need for custom DOS apps on the go, but as a general tool it was both too limited and too awkward.

(In an alternate world where calculators still made sense, it'd still have been interesting to see the 200LX form factor with hardware/software from the calculator division. They did at least get somewhat close to this with the financial calculator app.)
