Hello, Microsoft? Is anybody home there? Why the silence? We're still waiting (after several months) for you to make this right. Clearly this is a fairly widespread problem - I'm glad some users have no problem, but I have not yet personally met anyone
with an SP4 or SB that actually works as it should, and I've spent way too much time hanging around the Microsoft Store, so I've met plenty.
It's been reported that Microsoft uses Surface devices heavily internally. If that's the case, we can only assume that they're configured VERY differently from what your customers have to put up with. Here's a tip for you:
Make EVERY Microsoft employee with a Surface Pro 4 and/or Surface Book run their machines and do their work using ONLY what's available to customers BY DEFAULT through Windows Update. Do NOT allow them to use any other kind of PC to get any of their work done.
I'm betting the internal pressure may lead to a much faster resolution of these problems. It's quite obvious that Microsoft's priorities are inverted, since there is little to no care or concern over what
actual paying customers are having to put up with to tryto get their work done.
Lastly, you're getting away with this solely because you currently have no competition (other full tablet computers that have decent pens and run a real OS.) If you don't take care of your customers, they will leave as soon as they have an alternative.
Right now, the alternative is pretty much Apple, and with their current products, you have to spend more to buy both a MacBook and an iPad Pro to do the job.
Given the current problems and your lack of responsiveness, how many people do you think would buy or keep Surface Pro 4s or Surface Books if Apple introduced a "MacPad Pro" with a touchscreen that works with the Apple Pencil? (Even if
Apple priced it at $300-400 more than Surface's already premium prices - Apple seems to take the "it just works" thing seriously.) Look at the number of people on this forum who have given up in disgust and returned their SP4s or SBs and tell me you're not
well on the way to again making Microsoft the "anti-brand" it was just a few years ago...
