"The COOL-ER is Linux-based and is ready to deliver
with 128MB RAM, 1GB storage (Expandable to 4GB--SD Card) and its
Samsung S3C2440 ARM 400MHz processor.
"The only downside to the COOL-ER is that it has no wireless
access so all your ebooks have to be transferred to it via a USB
connection from a computer (Windows, Mac, Linux). This one lacking
option might hurt its initial uptake but the price point will put
it in more hands with or without wireless."
