Sometime around 2015 I promised myself to never buy a laptop with switchable graphics again. This has worked well so far.
But it never ceases to amuse me watching brands that position themselves as 'premium' spending pennies on firmware development team somewhere down in a basement compared to millions they spend on shiny marketing.
Likewise - I bought one laptop with "Optimus" in 2013 and swore to never do so again. I sometimes have to break out the desktop or rent a server but I have never regretted going iGPU only.
wow lots of us burned by the same thing apparently!
clever hardware suffers the burden of having lots of edge cases spread across a small customer base. going for dumb hardware that has lots of buyers is less exciting but statistically more likely to "just work".
for me: from now on, its either lenovo business laptops (which sell probably 10s of millions of enterprise users), or macs (which sell the same.)
volume > being clever
p.s. infact, even the lenovo TB docks are a bit shaky. ugh, more cleverness! i think sticking to their proprietary docks would have been the better play. with their volume, it would have made a better product.
