Equipment gets stolen easily. Never take expensive cameras to
places you do not know about or are traveling alone.
Use a P & S camera for most everyday shooting because you can guard
it very easily. Use the Nikon for landscape / nature photography.
Oh... I travelled a lot... I mean really a lot. spent a long time in many places from northern asia to SE-Asia, including india.
besides that never once something was stolen from me (I'm good at watching over my stuff...) I would never go to india, or any other place for that matter, with a P&S. sorry. I didn't buy into DSLRs and lenses, flash and stuff... didn't invest almost two decades into my photography to go back and use some slow P&S with crappy glass on. besides batteries for P&S die quickly...
A good advice is to get some sort of "incognito" camera bag... something which doesn't right away scream: expensive gear inside.
but really a P&S would be a waste.
I managed to break my old trusty film SLR on the route to india last time ... so I had to get some cheap p&S on the road ... needless to say, no manual controls, no wide angle, nothing.
I basically stopped taking pictures as most of the time I knew that the results will be nowhere near close to what I am expected to get.
and before anyone screams: it's the photographer, not the camera... true as it is.... a 35-70mm slow, small lens, and a small sensor, limited to iso200 if you don't want it too noisy ... an onboard flash which is not worth 5$ and all these things are serious limitations...
not to mention none, or rare & not-friendly, manual controls.
and as soon as you want to get rid of these.... well it's either a GOOD "prosumer"
"bridge" camera or a DSLR... and both are attractive to thieves almost the same.
I say travel as light as possible ... the 18-200 seems to be THE deal for your daily travel stuff (mine's on preorder

)... take one flash...
get a small manfrotto (the mini things) tripod... had it recently mounted under a 300mm

and placed the camera on a board... worked quite well.
whilst it wont replace any "real" tripod... it is small enough to fit in any small pack and still sturdy enough (even if not high) to find tons of use for it.
