I love my HP Pavilion dv7, model 3183cl.
I recently bid $200 for a used one on Ebay and ended up wishing I had bid higher to win. I wouldn't mind having a hot backup in case anything ever goes wrong.
I find that the touchpad works well for me as a mouse replacement.
I have owned many HPs over the years and strayed to other brands only to return to HP.
I, too, have trouble with my vision. I always run my browser with the zoom setting at "125%". This works great for me. Infrequently there will be a web page which doesn't handle the zoom well.
