I jumped in when the k100d was new. Value, size, and in-body SR swayed me, Olympus was a close second. The backwards compatibility with old lenses was also a consideration, at least in part because I support that design philosophy (whenever it's practical) as a way of not kicking your customers in the pants just for fun.
I don't put as much of a premium on SR anymore, and the relative value compared to other brands seems to have diminished so I don't know if I'd choose differently today. Size advantage is still there, my most used lens is a DFA 100mm macro and the C/N equivalents are relatively monstrous.

Totally agree here and wish I adopted a "Spend, spend spend" policy at the start.
