The Advent 4211 netbook was basically a rebranded version of the MSI Wind. Its successor, the Advent 4213 is something else. Blogeee suggests its a rebranded ECS G10IL, but it doesnt really look like one to me. The status LEDs and ports are in different locations. Im going to go with PC Pros suggestion, which is that the 4213 is an upgraded version of the 4211 with many of the same parts, but a new case and a few new goodies on the inside.
For example, it has a 160GB hard drive, which is twice the storage youll find on the Advent 4211. And the 4213 includes an HSDPA module for accessing wireless broadband networks. For the most part, the new computers specs look a lot like the older model: 1.6GHz Intel Atom CPU, 1GB RAM, and a 10.2 inch, 1024 x 600 pixel display in a 1.4kg (3.1 pound) package).
UK retailer PC World is selling the Advent 4211 4213 for £350, or about $620 US.
