Picked up one of these little Acer N2600 netbooks for my wife to haul around on the road. It's actually an impressive little machine, especially after some upgrades. Probably the biggest need is to upgrade the memory to 2 GB. They only install 1 GB in order to keep the price down, but that amount of memory is just too borderline for many needs. Memory is cheap these days, though, and it really can improve the user experience. Changing the memory can be a little intimidating as you need to take the machine half-way apart to access the memory slot(including disconnecting the keyboard temporarily). The previous comment had some tips on that.
I also did the in-place upgrade from Windows Starter to Windows Home Premium. The upgrade code can be purchased on Amazon for about half of the listed retail price. Just makes it a better user experience in many ways. The Windows upgrade probably took about 30 minutes from start to finish but then security patches needed to be downloaded also.
At first I thought the netbook didn't contain a microphone but that was a minor issue with Skype (user error). My wife is using an external mic plugged into the mic port to get a bit higher quality sound.
The wireless N is kind of a "light" version that is capped at 72 Mbps maximum download rate. It's enough for most internet needs, however, and it seems to have good enough range.
