NVIDIA considers external graphics accelerators

For years, NVIDIA has kept eye on the potential of external graphics accelerators, although nothing concrete is mentioned just yet. Many questions still need to be answered including whether the size of its target market is large enough to make such a venture feasible. While there are many scenarios to be considered, we think that the market is effectively very small. The future of portable computing is definitely not adding stuff via an external PCI-E bus. If NVIDIA sees an market opportunity, it can deliver a product very quickly, after all external GPUs are just like PCI-E based ones. Would you get one and at what price?
