Similar experience here in the UK
the main problem seems to be the docking station.
I paid 3000 GBP for a 1Tb Surface Pro 5. It worked well for less than 2 years.
The greatest piece of IT junk I have ever bought.
Here is the list of problems you will encounter with a surface Pro:
-the keyboard is not rigid; you would never think it is a problem until you try to use the SP has a laptop and you can't perch it on your lap
-you will not be able to plug in more than one USB peripheral at a time, even when you using the docking station. There does not seem to be enough power to make more than one peripheral run.
-the docking station will keep on charging the battery until the battery is destroyed. Oh well done, that is a most useful docking station.
-connecting an external monitor will be difficult and the table/Laptop may or may not recognise the monitor depending on the day, the hour, the month, in fact, it is unpredictable. I was using a DELL 32 inch monitor, works perfectly well with any other computer.
The weirdest thing that happened with the SP5 is that one day, staying in a very nice hotel by the sea in Portugal, the flappy keyboard and the arc mouse stopped responsding. There was somehow an interference from the hotel fridge (under the desk) that was upsetting them. A keyboard affected by a fridge? yes, that does smack of a bad design.
The worst thing was of course the battery. it was down to about 30 min autonomy. I went to the Microsoft shop on Oxford Street (London) and asked for a repair. I was told that was not possible because of the way the tablet/laptop is designed, but for the price of a new battery they upgraded the SP5 to and SP6 on the spot. That was not bad I suppose. At least I am saved the embarassment of putting this junk in the bin. It might have a few more years as a toy for some undemanding child.
Yes, that is Microsoft hardware for you: junk.
Do not buy a Microsoft PC is my new rule. Let others waste their cash. Back to DELL/HP...even the Chinese do better.
Adieu Bill, you are rich enough anyway.
