Are Instapaper 4.0 Enhancement Enough to Counter Free iOS 5 Safari Reading List Feature?

One of the risks of creating a great single feature app is that its target platform will integrate that feature into itself at some point. Instapaper for the iPhone and iPad is an interesting case in point. Instapaper, a $4.99 app, lets you save web pages for offline reading. The new Safari web browser Reading List feature introduced in iOS 5 provides the same capability for free. In response, Instapaper’s developer released a new version that provides significant enhancements and new features.

Introducing Instapaper 4.0 for iPad and iPhone

– Navigation redesigned for the iPad
– Navigation restyled for the iPhone
– Reduced clutter in Reading mode
– Hardware brightness control
– Look up selected text in Wikipedia
– Website footnotes converted to a popover
– Multi-selection of articles for management (archiving, deleting, or moving to folders)
– Friends panel can show all links posted to your Facebook news feed, Twitter timeline or Tumblr Dashboard
– Optional $1 per month option to search all contents of saved articles
– App Directory shows apps that integrate with Instapaper

Are these features and enhancement enough to counter the free Safari Reading List feature available with synchronization in iOS 5 and OS X Lion?
