I built my first computer with my 11 year old son in 1991/2, we had messed around with a second hand Commodore 128 for a few months but I don't have much memory about using it as it spent most of its life in pieces on our diningroom table.
Trying to keep one step ahead of our son by reading Personal Computer World we went on to build several more until he decided he didn't need my help and at 13 he started to build and sell his creations to friends and family.
Over the years he has updated and built new computers for me but my first shop bought laptop was/is a Samsung NP350V5C Core i7 using Windows 8. A heavy thing which wasn't good for carting about plus I was sure was dying. Although I replaced the battery, ditched Windows and my son tried his best to convince me it was OK I replaced it with an Acer Chromebook R13 CB5-312T - (MediaTek MT8173, 4GB RAM, 64GB ) which does everthing I want without have to deal with Windows.
My old laptop is still working well and I use it to do any art/photo work. It's now a full Chromebook with ubuntu installed for when I want to wind up my son.
PS. I am still a scardie cat when it comes to that horrible black screen thingy but I still find closing ones eyes and before pressing enter usually works.
