I'm not sure if this is even possible, but I thought I'd ask.
Briefly, to determine the usage of our product we need to know at least 2 things from our customer: what hardware they're running on, and what the base operating system is for said software. They may be developing on multiple platforms at once...so I'd like to give them a choice like this:
[fill in name of platform1] [dropdown list with choice of hardware] [dropdown list with choice of base OS]
[fill in name of platform2] [dropdown list with choice of hardware] [dropdown list with choice of base OS]
[fill in name of platform3] [dropdown list with choice of hardware] [dropdown list with choice of base OS]
A matrix won't really do the trick - and I could ask this as a series of multiple choice questions (one for hardware, one for platform) but that gets messy and makes the survey longer.
Any ideas?
