Are cases for the 1900 and 4100 series the same?

[gai-jin]

I have a vaja case for a hp 1910 pda... will it work with a 4155?

[Janak Parekh]

The 4155 should fit, physically, but the cutouts will be a bit off -- especially on the left side, where the record button and IR port were redesigned. If you can live with it, it'll probably be good enough. (I've only basing this on the E&B 19xx case, but I'm assuming similar dimensions for the Vaja...)

The vaja fits snuggly. I can confirm that Janak's assessment is accurate for the vaja too - the reset hole doesn't match, although the IR port mostly is visible through the open parts of the vaja case.
