For the gallery there's something on the "wish list" already, for the forum I've had an idea (dangerous I know) so I'll get back to you.

Operating Systems are always under attack from new threats, so maybe we should be thinking that it's a good thing that Microsoft are still supporting xp. Support for xp has been considerably extended, even though we have Vista and now Windows 7 that have superceded it.

If you don't want the updates, you can switch them off, but your computer may be at risk.

To go back to the original post, there do seem to have been lots of updates coming through over the past couple of days.

I guess if they are necessary it's better that we should have them!

The short answer is that the 645D will no doubt produce stunning images of a technical quality that will exceed 35mm-style DSLRs of all types.

That doesn't mean that all other cameras are now rubbish and it doesn't mean any of the overly pedantic stuff posted above, any more than when you read an old lens catalogue where almost every lens is described as "the most versatile in the line".

We all really know what the modern world is like and how products need promoting.

Ironically my son is an Architect and he loves using Macs, but is thwarted at work because they use PCs....

There are lots of things we don't "need" but on the other hand there's nothing wrong with enjoying what life offers. Providing of course it's not hurting someone else.

Yes, Windows 7 has been as stable and trouble free as xp, which itself caused me no problems.

All the 32 bit programs are still running just fine. Even Photoshop 7, which is getting a bit old now, runs perfectly well.

You sound as if you're over-cleaning flossie, and a lens pen isn't a sensor cleaner, so that might not be good.

Some sample images would be helpful.

The touch screen is something that has its place. It isn't a panacea, but it's fine on the iPhone and it's fine on some compact cameras.

As a keyboard it's 100% better than standard mobile phone keypads. As a full size keyboard I guess we would get used to it if that was the way it went.

After all, we now manage perfectly well without aperture rings.

I would stick to one colour space and learn the idiosyncracies of that. When you have the camera set to one, say SRGB, make sure that Photoshop is set to the same colour space.

Adobe RGB images may well look paler on your monitor, but it's not to do with exposure, rather the colour gamut itself.

Don't forget the monitor can only display the sRGB colour space - anything more is lost to view.
