Yes I noticed quite a difference when I went from the K20D to the K-7.

Another vote for Win7 here. Runs like a charm on both my laptop (which incidentally only has 2GB of memory) and my desktop.
No hardware compatibility issues or BSOD either

Another vote for Firefox here Andrew, I've been using for years much prefer it to IE.

A nice idea Tim, I like number one and two although I agree with points made about perhaps more balance from a less cloud infested sky

I also think that perhaps number one could benefit slightly from a raising of the exposure in the darker tones of that wonderful Hotel establishment

Definitely an idea (blue on blue) to pursue I think

I agree with David, numbers 1 and 2 for me are simply lovely photographs, congratulations

I like the general composition of your shot Andrew. All the versions have their merits for me. I also like this last close up you have posted.
A wonderfully sad image of decay.

I agree, when looking for a new D-SLR about 3 years ago (I was considering both Pentax and Olympus) I visited both LCE and Jessops in Guildford.
Even then Jessops were stocking hardly anything other than Canon and Nikon. Their reaction to Pentax and Olympus was quite dismissive and there was nothing for me to handle. I didn't spend long in Jessops
LCE were quite the opposite, they had demonstration units of both cameras which I was able to take my time and handle. They didn't push either brand just politely putting forward the benefits of both. A chalk and cheese experience that I remember well.

Doesn't seem any different to normal on mine (FF3.6)

You're right Gwyn, one is certainly enough

Come on then what was the patter? I need a laugh
