Well, had to buy a new phone due to charging problems.
Have changed from Nexus 5 to Pixel 2.
And.....I thought that would be it!
But.....the cable connectors have changed (USB Type C), so all of my current charging and data transfer cables are now defunct (house, car etc).
The chargers (house & car) are all now defunct as the connectors are wrong, but more importantly the specification has changed.
But to add to my woes, the SIM card, being a Micro won't fit into a Nano slot, so new SIM card needed.
That's all before I have even booted up the phone!.......No doubt Cortana is going to give me yet more grief!

Thus proveth what a lack of prior research on this/these purchases......

;-)

In my defense, I did a huge amount of research on the capabilities of the various phones offered. Many of the functions are not required by me, so didn't want to pay huge money for functions which would never be used. Nowhere did I find the details of SIM or connectors. It would seem that all phones, regardless of make, are now manufactured using the USB Type C connectors, so am just going to have to bring everything I have up to date.....as will everyone else who is upgrading. The annoying thing is that anyone in the house still using the conventional mini USB connectors will have to take care and not use / force my cables into their devices.
The last thing I have noticed is that the instructions say that I can transfer data from my old phone to my new one by connecting them with a cable (mini USB to Type C USB) which of course is not supplied (though has to be specific amperage output and support certain data transfer speed)! Maybe I might be able to do it via Bluetooth??? ....when the new Nano SIM arrives of course!!! And......it seems the 3.5mm jack plug for headphones is now obsolete, so yet another adaptor required to convert to USB-C!
Lots of chat on the Forums about the new type chargers as well.....with fast charge capability.....though the tech stuff is a bit of a grind to comprehend. Old chargers may bu**er up the new battery....apparently.

On the subject of Windows 10 updates...

Don’t Click “Check for Updates” Unless You Want Unstable Windows 10 Updates

As Microsoft revealed, only people who clicked “Check for Updates” got bitten by Windows 10’s file deletion bug.

"Bitten" means problems such as losing files, no PC sound any more (this can be fixed) and other hassle for you to have to deal with.

When you click the “Check for Updates” button, Microsoft gives you updates early, skipping a normal part of the testing process. If you let Microsoft control when you get these updates, things should go a lot better.

Apparently, there are some dodgy Chrome versions out there. One of them includes a PUP (a potentially unwanted program) which gives you intrusive infuriating pop-ups from an American news source which appear to the bottom RHS of your open PC window.

Chrome Version 70.0.3538.102 (Official Build) (64-bit) - is the one you should be using. Check the downloads carefully to see this is what you are actually getting.

To check what version you have actually got:

Left click on the 'three little dots'.
Left click on Help.
Left click on About Google Chrome

Chrome is a 'Google browser' and you can Register your usage of it when you sign in to your Google account. This allows you to 'synchronise' your usage of Chrome for when you use other machines, simply by signing in to your Google account on those other machines. This allows you to have identical browser settings for Chrome on each one.

About 60% of users now use Chrome, basically because of its excellent 'app add-ons'.

eg. Last Pass; Adblock Plus; Show Password; Coupert; Speedtest; etc.

All of your Bookmarks (Favorites) stay in the same positions on the Chrome browser bar too.

Latest Chrome version is now:

Chrome 70.0.3538.110 (64-bit)

You might need to check your own version of Windows to see if it might actually have an expiry date.

(If it does have an expiry date and then does start to expire on you, well, the experience is not going to be pleasant)
