Do I need a new laptop/tablet?

I have an old Toshiba also and I couldn't get on the internet with it. it was full of virus's. had it cleaned out and it still works fine. I use it on trips too. I bought a new Dell 17" screen and it is heavier than the old Toshiba. I also have three tablets, every one of the kids like them, I'm not a fan of the tablets. too old to see the small screens. DW uses a tablets to do her reading. she gets books from Amazon. now a days you can keep every thing charged up through your power points in your truck.
