EReaders are starting to really take off thanks to the Amazon Kindle. The big catch is that most of the readers on the market lack the key Kindle feature that makes it so popular, namely wireless connectivity.

Astak has announced a new 5-inch Pocket Pro eReader that will retail for $199. That sub-$200 range is thought to be the sweet spot for eReaders. The device also supports Adobe DRM PDF files along with 20 other open source formats. The 5-inch screen supports 8-levels of gray scale.
