Some cons as reported in linuxdevice:
"There was a pretty noticeable one- to two-second delay between an input and an action, which may grate the nerves of impatient Web surfers. In addition, flash-based sites such as YouTube are off-limits."
"On the downside, processing power is fairly weak, and the integrated Opera browser is not completely stable, especially with highly complex sites such as CNET and CNN."
(What processor is it?)
