Ditching your DSLR?

I think a lot of people are sick of lugging heavy bodies and lenses around but, is it time to ditch the DSLR yet?

If you bought an X Pro1 or EX1 did you ditch your DSLR, if so what do you miss if anything?

Looks like the mirror-less cameras fit the bill up to 800 ISO but they do lack telephoto etc

Or did you keep both, it would be good to hear of your experiences
