I got myself a Sony HDR SR1 yesterday for 861 quid, so I've just been able to play with it yesterday evening.
This is my first camcorder, so I'm a novice user.
I've waited for a camcorder like this because I just hate floppy's and tapes etc, so for me a HD is just perfect. I also didn't like the resolution you get on a normal camcorder and since I'm going to buy a Hi-def LCD (Sony 46x2000) I wanted a resolution of a camcorder which uses that resolution or at least half of it since the recordings are interlaced.
My first reaction is just how easy it is to use this cam, I could teach my girlfriend to use it in a matter of minutes (normally it takes ages to try and learn her to use any kind of gadget). Also the touch screen works very well, just touch the recording you want to see or delete etc, very straightforward. Transferring files from the cam to your pc is very easy as well, via USB2.0, you need to initiate the transfer on the camcorder. In you computer an extra removable drive appears, so I guess you could copy the files straight from explorer, haven't tried that yet. Some people complained the cam not having 1394, I guess USB is cheaper and it also does the job very well. Making still pictures while filming was very easy, I haven't compared the quality with my digicam, the only downside was that there is 1-2 seconds delay between pressing the button and taking the actual picture. I've disabled the flash, it just gave an ugly white picture which looked horrible, hopefully some adjustments can be made to the flash (intensity etc).
I'm don't think I'm going to use this cam in SD mode (I haven't bought a Hi-def cam for nothing), so I won't be able to tell you anything about that.
I was a bit surprised when I played back a hi-def movie on my PC, it had a peakloading of 95% using both processors on a X2 4400+ AMD

, This was under very static circumstances, no movement, I wonder if there's a lot of movement if my PC can still handle it without framedrops? This is the first time I actually need my dual core Athlon. Since I only have a 3500+ in my HTPC when I buy the 46x2000 I think I'll need to upgrade the processor, or someone writes a more optimised decoder for this fileformat. Considering the aforementioned the processor in this cam is pretty amazing!
Although I don't know much about it, I thought the lighting of a recorded movie was very good, if I turned into a lightsource and turned away from a lightsource I didn't see all kinds of dramatic exposure adjustments which I once saw when I was using someone else's camcorder. When I made a recording yesterday evening in our room with 2 faint lights and the television set emitting light, I was able to film my girlfriend in very faint light conditions, OK the picture was noisy but still....
I'm going to use this camcorder on my skiing holiday, but I want to know the ins and outs before I go. I am a bit worried how this camcorder will perform under very cold conditions, the spec says 0 degrees is the lowest usable temperature the cam can work in. Last year it was -16 during the morning in Austria, I wonder how it will work in those circumstances. I've bought 2 extra big battery packs QM71D with a quickcharger to hopefully help dealing with extremely low temperatures, the only disadvantage is that the battery sticks out the back of the cam. To prevent damp entering the cam, I will be using a plastic bag when I go inside. Another worry is that I only have one week of skiing experience and I'm going to put this baby in my rucksack, I hope it will survive my falling

, but I haven't purchased it just for show. I wonder if using a polarisation filter will improve the picture quality when filming in the mountains at high altitude, anyone an idea?
A thing that could be improved on the cam is the fact that you can't use the ring to zoom in and out, you can use a lever on top of the cam but I'd rather used the ring but maybe I just need to get used to it. The eyepiece on the viewfinder could be a bit bigger as well, especially for users, like myself wearing glasses.
The only worry is that at the moment no editing tools supports this file format, but hopefully that is going to change in the future. If anyone has news on that please post it in this threat. If the editing tools are available I hope they put a lot of effort in optimising the encoder and the decoder, since merely playing this file format gives such a high load let alone if you start to edit this fileformat, I hope I don't need a quadcore for that? I've invested enough for my taste in a reasonably fast computer. Of course you can always convert it into MPEG2 according to this forum:

Any fellow HDR SR1 users please let us know your experience with this baby, I know this thing is selling, so I can't be the only user around!
