SATA 6G mobile computing is just going to have to wait, but obtaining USB 3.0 is not as far away as you might think. VIZO recently launched their new SPEED-UP ExpressCard that features two USB 3.0 ports into a 34mm wide card that resembles what your first PCMCIA wireless card looks like, only a bit thinner.

Obviously the technology has changed a bit since your old WiFi card. That slot on your notebook is now tapped directly into a PCIe 1x lane and is capable of transferring data much faster now. Most likely on your notebook you have a double row 54mm slot that is much wider than the card you will see here today, but there is little need to worry; ExpressCard has been around since 2004 and most notebooks are shipping with ExpressCard 2, a PCIe 2.0 1x lane, but unfortunately for me my T61p uses the old PCIe 1.0 technology, but it should still be fast enough to blow the doors off USB 2.0 and give at least 100MB/s data transfers.
