So many of you were so helpful in solving my photo storage/viewer problem that I thought I would post the end result which I am extremely pleased with. My problem was that my new 50D and 1Ds3 cameras had overwhelmed my Epson P-4000s and I was looking for a good compact alternative for travel. The larger capacity Epsons were so expensive and still so limited in capacity that I decided against buying them (I always used 2, one for the images and a duplicate copy for safety) Pursuant to many suggestions, I bought an Asus 1000HE, card reader, Western Digital Passport external HD and installed Breezebrowser Pro. I download using the drag and drop method as suggested. I download directly to the external HD (I may add a second external HD for backup copies but have a bunch of high capacity CF cards as 1st storage now.) Avoiding downloading software makes it very fast--about 2-3 seconds per RAW file. I tried a couple of free viewing programs but found them too slow. BreezebrowserPro is fast and really nice software for viewing images. Having email is pretty nice too! So thanks again to everyone who replied to my prior post. And I hope this summary helps anyone else in my shoes.
You can zoom by spinning the wheel on my mouse (forgot to mention I got a Logitech mouse too) but the real neat thing is the magnifying glass. Works like Bridge's magnifying glass but is much better. It helps to read through the Help section which is really useful.
There is a list of keyboard shortcuts in the Help section. I rarely can remember them so I don't use them much but there may be a zoom function there. Slideshow works great. I am really loving BreezebrowserPro the more I find stuff. How do you like Windows 7?
How do you zoom in in BB?
