I got me the RAM for my new Acer Aspire One D270 Netbook bought (with Windows 7 Starter) because the built-in 1GB were a bit choppy. The performance boost is clearly noticeable, the netbook starts more quickly and is still rock solid. The whole system feels much better performance because less is outsourced. The delivery time was great. Saturday afternoon and Tuesday ordered already in the mailbox, not get any faster.
