My tuppence worth:
The Bee (which I have):
Plus points: It is smaller than all the others mentioned above (Babyjogger is narrow but long) which is great for buses and crowded cafes and narrow Victorian hallways. Also lighter than the others so good for getting into and out of the car and carrying up steps. Very extendable handle, good for different size parents. Curved single handle is easy to push one handed.
Folds up small and in one piece. Faces both ways. Seat extends for toddler use.
Downsides: the tiny wheels get stuck in potholes. Clamshell seat rather than bucket seat, which is a bit less supportive when they are in early sitting mode. No carrycot (though I gather there is a new version coming which will have one). Personally I don't think the lack of carrycot is a big deal. Babies are very cosy in the cocoon and it's 99% flat.
Cameleon: Lovely except I HATED the brake. It hurt my fingers every time I tried it. If it wasn't for the brake I might well have got the Cameleon.
Babyjogger: Didn't like it at all. Not parent facing. When on full recline it bashed my legs. Very long which is a pain on buses (according to friend who has it)
Icandys: I wrote most of them off because the hoods make a loud click click click noise. Best way to wake a sleeping baby
I also hate all the blingy metal on them. However the Cherry is nice - can't remember why we wrote that one off to be honest.
Uppababy Vista: Great buggy - great hood, basket, carrycot, nice chunky wheels - but HUGE so not good if you are a short person IMO, or if you don't have much space at home. Its baby sister Cruz is smaller but handle still very high (and the handle is a bit rattly I find, plus the suspension's not great).
Overall I'd pick the Bee if you have concerns about the Cameleon being big and heavy - it's the smallest and lightest decent newborn pram you can get. However if you personally don't find the Cameleon too big and heavy (and if you don't hate the brake!) then get that. Everyone's perception is different so don't go by your friend's concerns. I am 5'3 and wanted something really small.
