What? I mean how on earth do you come to a decision like that without having extensively used both.
Besides its not "mirrorless" vs. dSLR. There are plenty of mirrorless cameras with EVF, which the K-01 doesnt have, while the K-01 is not especially smaller than a dSLR.
It's 2012, you are sitting on an MX and four fairly unremarkable vintage lenses. Clearly you are conservative and cost-concious. You contemplate your next step...
Running out now and buying a K-01 at full MSRP would seem the absolute worst option.
There are so many others:
1. Keep going. You have a nice, full-frame camera and an optimal lens selection. Excellent image quality, retro chic.
2. Buy a K200 or K10D. All the fun and convenience of digital, your lenses all still work, costs you $200 or less. Lenses are less ideal on the new crop, but you can "upgrade" in time.
3. Sell all those lenses and buy a Nikon V1. EVF, 28mm prime lens, and with the tele-zoom you have the same focal lengths as you are used to with the MX. Nikon 1 is a bit of a bargain right now and is small and convenient.
4. Sell your lenses and get a K-m/x/r. Same size as the K-01, cheaper. Get the double zoom kit, and the DA35/2.4. The camera actually has a viewfinder, and those three lenses should have you covered over the same range of focal lengths you are used to. Lose some image quality vis the old Pentax Ms, but full convenience of metering and autofocus.
