you can just have a Microsoft surface pro or an iPad pro held by one of those tablet holders and then use a Bluetooth keyboard and mouse on your laptop.
I used a first notebook 20 years ago, not a really cheap one, but battery failed after 4 years, not replaceable. Next an expensive Ultrabook, same with battery, touch display, and failing period. Next a netbook, battery, touch-display, and key one by one failing too. Last, a Surface-like tablet, with replaceable keyport. Crtl key hanging. Considered irreparable by customer support again, and given new price back in exchange. Android tablet's battery is starting to fail after 3 years too now.
I'm simply fed up with such wastes of resources and money of having to trash a complete computer because of perferals. Just saw a tech video of how difficult it is made by the manufacturer to repair even more expensive iPAD or surface pros. Besides, many of us don't have a budget for. I'm glad for you if you do.
Ps when it comes to flexibility
That is my main point. Flat rent went astronomical here. Therefore, I'm building an ultralight-weight tiny house, to be moved by a cargo bike. Which isn't easy with my still low energy envelope (max. of 4 hours daily manual work) or cheap itself. But with lack of having to pay such horrendous rent, amortized in 2 years only. Where sustainable heating and electricity suddenly is an important factor to consider too. Beside sustainability, environmentally friendliness, low energy-footprint, and budget-wise - overall. Already in my flat with solar-panels on the balcony my energy-bill is negligible now.
I therefore think, considering
all factors involved with an ideal computer-setup in bed, might help others to decide make choices with less financial repercussions. Very pertinent to ME/CFS patients, some with no financial resources at all.
