On the right side are a memory card reader, audio in/out jacks, a USB port, a Kensington lock slot, and an Ethernet port. The Aspire One D255 has a standard array of netbook ports. The air vent belched out 107-degree air, but not in the user's direction. However, all that heat has to go somewhere. We consider temperatures near 95 degrees Fahrenheit acceptable and those under 95 extremely pleasant.
Even after streaming a video at full screen for 15 minutes, we measured the keyboard at just 84 degrees, the touchpad at 85 degrees, and the bottom at a chilly 89 degrees Fahrenheit. The Aspire One D255 stayed relatively cool throughout our testing.
