I'm happy with the way it works, for the most part. Bit of a shame it has to use external authentication, but I use a secondary account for that anyway. The fact that some features are pay to use is a bit irritating, and I haven't yet decided whether they're worth it. I am willing to pay for services that provide value for me - they're a business, and I understand their need to make money to provide the service - but there isn't much compelling in the pro feature set for me. Possibly Evernote integration, but it's not that much hassle to click through to the website and clip it from there.
Bottom line, though, is that it's better to be a paying customer - at least you know the business has a vested interest in the product. Same with Evernote vs. free options. They make their money from users who get value from their products.
I was also reasonably impressed with Feedly's transparency over the recent DDOS attacks they (and Evernote) suffered.
