I only purchased the Nexus 5 which dissapointed me so much that I never switched back to a nexus or a google product. I would only be using google.com for the rest of my life but not any other product.
Putting so much hardware into a compact design will obviously come with the de-merits. It's good that the issue was taken into account and solutions were being provided, instead of companies like samsung where after their NOTE 8 became a headache to the world, then only they recalled it.
I never used yahoo messenger in my life, I mean yahoo itself was a pain to use when my first account was created, I remember my friend creating an account for me and swearing hard lol. He gave me alternatives but I liked the word "yahoo" and there we go. I can see yahoo mail dying as well.
