My wife has just parted company with her 300D (AI Focus driving her nuts - and no, she wont have hacked firmware) and while she waits for my 10D (as long as it takes to get my 1D MK-II) she has bought a Pro 1.
Well, I have been playing around with it and for the price it is not a bad bit of kit. But, oh dear, just like other P&S I have had in the past, the low-light noise is terrible. I'm obviously too used to the DSLR's where I can get lower noise at ISO 1600 than the Pro 1 has at ISO 50. Apart from that and a bit of PF and CA, it is OK, nothing special, just OK.
I'll be taking it on my trip to Nevada in a couple of weeks, along with my 10D (minus Big Ed and with 17-40 and 50 1.4) just to see how the two live side-by-side. I wondered how many people still carry a P&S or even find a use for one these days? Do things like the jerky EVF drive you nuts compared to your DSLR viewfinder (it does me), or are you comfortable using it? For a brand new camera it is like taking a step back a couple of years in digital cameras, to me anyway.
I only shoot at weekends and some odd special assignments, so a daily carry about isn't something I really need, but the Pro 1 may stay if I can justify keeping it in my briefcase just in case the occasion arises where I need a camera.

but, I've been out a lot since getting my G5 and with a bit of patience it really can deliver very good quality - even hand-held and wide open.
