Barnes and Noble is intending on releasing a new firmware update for the Nook Simple Touch and Simple Touch with Glowlight this June. The 1.50 update is poised to bring a new email client and a new internet browser. The e-readers themselves have a web-browser buried in the search function, but most people were completely unaware of it. The ebook store is also undergoing a refresh and will have a new UI.
The Nook line of e-readers has seen a wider appeal as of late, due to the recent price reductions in the UK and US. Google Play on the Nook line of tablets has been drawing industry wide attention and many users we talk to are claiming they are buying one for the first time, or switching back to the brand. B&N is hoping that a more accessible e-reader is will appeal to people on the fence.
Barnes and Noble has always had internet browsers in the e-readers and I will bet that they will not tweak it very much with the public release. A solid email client should appeal to people who are in book clubs, or need to check in to work every so often. The Nook line of e-readers does run the Google Android operating system, so adding a few new features is really not that hard.
