Acer ‘One’ reviewed: Gets 6 out of 10
On the bright side, the machine’s three cell battery is good for a little over two hours of battery life, which beats out the Eee 900, and you can increase the in-built 8GB of storage by adding a SD(HC) memory card. Interestingly, the memory card’s storage is added to the machine’s main memory, not as a separate storage device.
So there seem to be a few tradeoffs, but the expectation is that these Acer machines will be priced really aggressively, so it may be worth it for some people.
