angstrom: Ugh, somehow I knew that there would be a catch. I've heard some bad things about DRM, but please tell me SecuROM isn't that bad on those games and they won't wreck my computer. Their prices are too low to resist. Hopefully Armored Princess will also make it to GOG in the future, though I can't say if it even will be on this site anytime soon.
Armoured Princess will probably be released at least a year from now. But It almost certainly will make it here eventually. I suppose it depends on whether or not GOG get EA on board in the meantime.
As for the the DRM, the fact that it's SecuROM doesn't tell you very much as implementations of SecuROM could be anything from a simple disc check through to something which is so invasive that it's essentially malware. It's all down to the publisher as to what features of the DRM are used.
The only advice I can offer you is to ask GG support about specifically what the DRM does. Such as if there are limited activations, if so are they refunded and how are they refunded.
