Keeping In Touch

I'm trying to decide what to do about getting a computer for when I'm out and need to check on my work. Not somewhere that I can take my laptop, or have access to a workspace. More like when I'm in my car driving around, and waiting on appointments or running errands. I use my phone hard during those times, but that is still small and cramped. I don't expect to be able to do a lot of things, but I'd like a much bigger screen to view emails, and go to websites. I've been looking at netbooks. My husband has one, and I've used it. It is a lot better for light work and browsing than my phone, and bigger then even the largest phone, or even 'pad'. I am leaning toward one of those for keeping in touch when I'm out.
