Sorry to keep bombarding you with information!

I believe you said you have problems with your hands hurting, etc.. too.. mine are numb and what helps me a lot is to use an external mouse instead of the mouse pad right on the laptop... (they are very inexpensive) - also, another inexpensive but potentially helpful item - a USB hub that has extra usb ports - just plugs into a port in your puter - and then you can plug more items into the hub (the one I have doesnt have to be plugged into an external power source - some do - which is less hasssel) - and allows me to leave hooked up my printer, scanner, mouse, I leave the camera cord in to download photos, and also can use it for MP3 player etc.......
