The SLR is big but takes great photos, what do you do with you travel and want to go light?
And what about the lenses I have?
Novoflex has introduced adapters for EVIL cameras (SLR type mountable lens cameras' without mirrors making them very small)
Your Nikon, Canon, Sony etc lens will mount on Olympus PEN, Panasonic G/GH and the new Samsung NX.
Get a small EVIL camera and with the adapter use all your lenses too! The adapters will give full functionality, aperture control needs to be done manually (Will not work with Canon EF lenses), but it's a start.
