He just got a new one and ask if I like it no the touch pad is terrible and there are all these pop up things its like a kids movie with 3D. Dreading the day I have to get a new one, my adult daughter laughs she is on her 5th since I moved here. You have to understand I lived in India back in the 80's and 90's when you could not bring certain Items in without paying a hugh tax. So my first laptop had a key board in Hebrew because it was easier to bring it from there LOL. Geting back to the external hard drive the one you use for your lap top is more like it. Is it easy to use? Do you know if I could use it with xp professional? I am going to try to look it up. How do you like your Camera and I know the quality is probably really good when you blow up photos are their must have features I really need? My wedding pictures were done in raw format, I don't know why she did them that way but they are awesome.
Well, I do understand what you mean about not liking to change computers (or CELL PHONES!!!) but I do like to upgrade my camera bodies, and I always upgrade PS with each generation. Unfortunately, that, to some extent, drives my need to upgrade computers too, though when I do, I try to think ahead, and get the most powerful machine I can so it lasts me as long as possible.
The Passport runs directly off a USB connection, and it will work on any computer with a USB port. It's just a hard drive, so it really doesn't matter what operating system you are using. The WD My Books are also USB, but they require their own power source as well, so there is one extra wire... Not a big deal, really. The biggest difference is that you pay for portability.
The My Books cost about $79 each, and the Passport is about $125 for the same size drive.
As far as upgrading from the 20D is concerned, if I were you, I would NOT move to the 7D, I'd suggest getting a 50D if you can find one. The 50D is an AWESOME camera, as far as I'm concerned, the best XXD that Canon has made. I had no intention of buying the 7D until my husband dropped and broke my 50D.
I do like the 7D, and I'm starting to get the hang of it, but there is would be a relatively steep learning curve from where you are now.
I KNOW you can EASILY slip from a 20D to a 50D because that's what I did. The controls are very similar, but the IQ is much, MUCH better, and the noise at high ISO's is controlled much better too. When my husband broke the 50D, I had to go back to shooting the 20D while I was deciding what to do. I found the screen on the 20D to be SO small, after getting used to the 50D that it felt almost useless.
Or you could go with the 60D... it's going for about the same price as the 50D's, even though the 50D is discontinued. The 60D is plastic, but I got to handle a friend's on a recent trip, and it has a pretty solid feel. It also has an articulated viewfinder, which she liked a lot... I don't think I'd use it much. Both the the 60D and the 7D shoot HD video if you're into that... I like a camera to be a camera. I don't need it to be a video camera or a cell phone, thank you.
But ALL the new models of ALL the camera brands are coming with video these days, so I guess Canon had to do it too.
Oh, and any lenses that fit on your 20D will still fit any other XXD or the 7D.
As far as shooting RAW is concerned, since a camera can't "see" the same amount of dynamic range that a human eye can, it is easy for a scene to either have the highlights blown out or the shadows blocked up. Shooting RAW gives you the opportunity to recover information in these areas that you couldn't if you let the camera's middle-of-the-road algorithms make decisions for you. It does mean some extra processing, though. One you've shot a sky that looks "bald" as a JPG, and seen the detail that is actually there in a RAW file, you're a convert forever.
