Alas, their quality has been going down recently. The most important feature - keeping the location inside an article between app invocations, is not working. For long articles, if I stop in the middle and want to resume later, there's a 80% chance that Pocket will happily set me right in the beginning.
Besides, their rendering for articles with code sucks, so I almost always use "web view", a decision Pocket also forgets every other time.
So I end up using Pocket as a convenient keyboard-shortcut to save articles, but on my phone actually open them into Chrome, which has no problem remembering the location in a tab.
