Torn over the hotshoe? You want portable then you want to carry a Speedlite to mount on the camera? Get the Sony.
That makes sense. I guess if it's portable a speedlite does not help. Also it will actually fit in my pocket and aid for rides and candids. I just did not want to work with another system but hey thats what I have to do.
I have lowered my gear for my vacation.
At this point
50 or 40mm
batteries and sd/CF cards
Considering Tamrac Evo 6 or lowepro Fastpack 350
While I want the 70-200. It is too much for a vacation I think. As it is I don't even want to think about that heat and all that gear around my neck and back.
