This month’s issue of Wired Magazine (guest-edited by J.J. Abrams) has reviews of four e-readers, including the Kindle 2. It rates the Kindle at an 8, citing the poor PDF support and lack of an SD slot as negatives. The other e-readers reviewed are the Sony PRS-700, the iRex Digital Reader 1000S and the Astak 6″ EZ Reader. They received a 6 and two fives, respectively.
