That's IMHO the big problem with all app market places - there's a glut of solutions for every problem. Nobody can be reasonably expected to sift through this, and so we end up with lots of small apps.
Corollary to that: By now, it's almost a waste of time to develop an app in a segment where a cheap clone can be knocked off in a few weekends.
I'm a former Instapaper user that loves Pocket. I was barely willing to try Pocket since my queue was already in Instapaper, but I was tired of my chosen platform being treated as second-class. Android Instapaper apps sucked except for the excellent PaperMache (Yes, I have an HP TouchPad), which was just slow on Android.
So, I moved to Pocket and I love it. The text formatting on my CM9 tablet is GREAT by default, keeps images (in offline mode, too) and has a VERY attractive grid of unread articles that shows an article thumbnail. It's a much more enjoyable experience.
That said, I bought Instapaper for and tried it out. I'd be happy with the new Instapaper app had I never switched to Pocket, but Pocket is just better than Instapaper in their current iterations. I'm definitely glad there's competition on Android now though.
One Instapaper feature I miss though: auto-tweeting articles that I have starred.
Ultimately I liked Pocketso much I paid for the pro version, just like many others[1]. Their business model seems pretty sound and they have a lot of users and the product is excellent. What is so exciting about Instapaper?

Also I never understood the appeal of instapaper, what exactly does it do better than pocket? I never used instapaper, so any answer would be appreciated.
(I've been using Pocket since before it was Read-It-Later on my iPhone and paid for it on iOS and again after switching to Android, maybe Instapaper does more now).
What's interesting about it, is the things people will decide to go without, due to something being free - when really the price difference of Free or $5 is fairly negligible.
( I don't use either service... merely an observation )
