This is a most excellent place for technology news and articles.
I hate that LG left the market. A LOT of innovation came from them, including a lot of quircky (and often cool) features. They experimented a lot which didn't always work out, but often it did work out great and it made their phones a lot more exciting then most other brands. Because of this a lot of features that are now the industry standard, like having a wide-angled camera lens, were popularized by LG. And yet, somehow, most people don't know this and always saw it as a lesser brand.
