Speed worth talking about, The PCI Special Interest Group has started a plan to develop a variant on PCI Express 3.0 that would challenge the Thunderbolt format from Apple and Intel, its planning for a 32Gbps PCIe cable. This cable will able to channel power as well as data through to devices up to 10 feet (3m) away. They are looking at shipping products ideally before June 2013, so if your buying a laptop around 2013, might be worth holding off to see if you can get this connector, It could be like getting caught with USB 2.0 just as USB 3.0 comes out.
