It arrived this morning and it's never leaving my sight!

Sounds like an awesome trip though - if you don't have the gear I could always take your spot…
FWIT - I've seen tests of the 7D in extreme conditions and it held up without a problem.
We could always apply to go together

The trip's essentially free, it's about three months and the only requirement of you is that you help out with manual labour when you land. According to my uncle, who's been in contact with some friends that have gone back over recent years, the manual labour isn't all that intense, either, since most of it is handled by machinery.
The only other real costs for your participation is that things like laundry detergent has to be bought on the ship and any alcohol or snacks/sweets you want have to be bought at the ship's bar/tuck shop.
I was hoping to win a Canon 60D in one of mycamera.co.za's competitions which I might have been able to pay a difference in on to upgrade it to a 7D, but Kobus Tollig ended up winning that one.
At the very least, by the time I do manage to make this trip, the 7D will still be very relevant, so there's no reason I wouldn't consider it closer to the time - at which point it should also be cheaper.
I'm also considering approaching Canon SA to see if they'd be willing to sponsor me with the use of some of their lenses for a trip, though I've got my work cut out for me becoming a photographer they'd want to put their name to before there's any chance of that happening.
Also, I'm serious about applying for the trip together.
at 4k the s100 is a no go im afraid. this is the dilemma and causing me so much frustration. i have my phone with me always. if theres something cute happening, i want to snap it. ive learnt over the years that it doesnt matter what equipment you have in your hands, if you timing sux your picture will suck.
to get back on track. the question is. would you carry a p&s to snap pics of your kid/s thereby ensuring you have an additional gadget or use the convenience and availability of a decent camera phone?
ive seen prints produced from the n8 and they are more than satisfactory. the pureview must be insane but not at 450/pm. the s2 is well priced but im not sure of the quality. will have to check a n8 vs s2 camera shootout to compare.
I would go P&S any day, especially if I already had a Curve 8520, which more than covers all my needs out of a cellphone.
The primary reasoning would be the breadth of controls available to me on the P&S facilitating my ability to take a photo how
I want to take it, not how the camera or a camera phone wants to take it.
That and raw. Worry about getting the shot now, correct the white balance and slightly-off exposure later.
