My backpack - I use a JanSport Antics Series Driver 8 Wheeled Backpack . It has three large comparments, a smaller wallet-sized pocket, and a good size mesh pocket on the side that, as you can see from above, I use as a cup holder. In the larger pocket, there is also a sleeve to hold a laptop. This pack got me through college holding all my books, notebooks, supplies, audio gear, bathroom gear, and the occasional soda. It is also on wheels and has a telescoping handle that turns it into a rolling suitcase for travel. It also fits my Invacare Storm chair perfectly and easily fits into a plane's overhead compartment. I've found this pack to be much superior to the packs that are supposedly made to fit wheelchairs.
Our camera - We actually use a couple of cameras, but this Canon PowerShot A590IS 8MP Digital Camera with 4x Optical Image Stabilized Zoom has just as good a picture as our larger Fuji Camera but in a pocket sized package. With a 2GB SD chip, it can take over 1,000 high-quality pictures. We started using this camera on our France and Germany trip in September, check out the images from that report.
