Not writing this to convince you, I don't care what you use, nor do I gain anything from you using it, but to help educate others which might run into the same things as you did:
That's what really did it for me, the web browser. Everything is rendered awkwardly.
When you open the Browser, Pull Up the three dots and enter the Settings, change from Mobile to Desktop - Voila.
The Browser renders pages perfectly as they are presented to him ("webkit" is nothing, it makes no difference to anything or on how something is presented to you (rendered)), the problem is that some webpages send it (the browser, when it is on "Mobile Site" mode) the old Candybar-Smartphone/PDA/Windows Mobile version of their mobile sites, instead of the new touch-versions.
For Facebook for instance, go to touch.facebook.com, or just visit the normal desktop site (which I find to be better). Twitter displays (as I've read) an ugly mobile site, but I've read that that has also been fixed.
The most ridiculous case is google, which does that when you visit the "Desktop" site, it sends you to the ugly pda-mobile site, instead of the nicer touch mobile site it displays when you visit it with the toggle on "Mobile".
But I have it on Desktop anyway, as google is still useable and I don't use it as often, since the integrated Bing search is much better for most of the things that pop into my head and I want to look up quickly (that one actor/movie, this thing I heard, how does the actress with the name xyz look again?, that old song/band, this xyz), it is just as good (honestly, if not even better, but I'll explain that in a sec) on the up-to-dateness and just not as good on the establishment/POI front.
But the Bing search on Windows Phone is completely different from the web version of bing, and MUCH better at that, probably because it sources its info/predictions etc from the people who use it on their phones and not like the bing web which probably only (if even) sources its predictions etc from the people who use it on their PC, and I frankly don't think it does even that, the suggestions when typing are years old, same goes for the results, and there is no filter option for time (last 24h, last week, month etc) so that you could get more relevant or up-to-date results, while the bing search on WP even gives me some of the newest (not even a week old) things (like quotes or specific constellations of words, eg a movie title, two celebrities who currently are mentioned together, a new car model name when you type the brand etc) as suggestions while I type the first word, you simply just see that it is up to date on TODAY, not last month or year.
Regarding the up-to-dateness for example. I am comparing this to google (web), bing (web) and bing (wp). I enter the name of a show and an incomplete part of a quote from an episode from a TV show from yesterday, and the results look like this:
Google gives me nothing of relevance unless I filter the search for "Last 24 hours", then I get a couple of pages where the quote is mentioned in regards to that show. Sometimes it gives me the relevant stuff right away without having to filter it, but that is mostly if it's specific enough and not just a broad, general sentence in conjunction with a tv show name, and mostly only after a few days or only if it's so popular that millions of people have searched for it.
Bing (web) doesn't give me anything even close (not even just the wiki or imdb page for the show, which is something that should always be on top, especially if it can't provide anything for the second half of my query, the quote), nothing even on the show, and there is no way to filter for time, so you get what you get (year old random stuff which has nothing to do with anything you search for), no influence to change anything about that towards finding what you need.
Bing (Windows Phone) gives me the relevant sites, which I had to filter for to get in Google, right away, without having to do anything except to type in the exact same search query. And this is really no isolated case, I have been witnessing this increasingly in the past few months. Also, the suggestions are (at least in my case) always top notch, and what I am actually looking for (what is relevant right now around this time) is most often among the three suggestions, while on Google (web, on my pc) the query (for example, a name of a new/currently relevant actor/actress/singer) that is relevant now may only be at the bottom of the list of the suggestions, if even there. 95% of the time I had my Windows Phone, I always used the google search in the Browser, but in the last few months, I have almost completely switched to Bing search, as it is much better.
The copy and paste was awful. I spent a good 3 minutes trying to copy/paste a link and gave up.
For links, just tap and hold on it, then select "Copy Link" from the pop-up menu. If you can't tap and hold (if it's not recognized as a link):
You just click at the beginning of what you want to copy (say, the http), when you click you select the whole word (or put the cursor on the space before/after a word), and pull the little arrows to select everything you want, and when you want to select specific letters, tap and hold and a cursor appears that you can place exactly where you want it. Then just click on the small circle copy symbol. It's actually pretty easy and simple.
Try it out before you sell it, so you don't embarrass yourself in real life when you start talking smack to someone who uses a WinPhone and knows how to use it properly.
