An 8 port gigabit switch is £20. An 8 port 10Gb switch is £600. A gigabit NIC from a recognised brand is £6. The cheapest, unknown brand 10Gb NIC I could find is £200. The answer is price versus performance making sense.
The sweet spot is about 3-4 times the price for 10 times the bandwidth. Right now 10GBase-T isn't even close at 30x.
As the presentation indicates there are genuine use cases in offices and, in time, homes, for 2.5Gb and 5Gb. The idea that it's because incremental upgrades are more profitable seems strange given it's not incremental, 10Gb has already been released, it's just too expensive for the applications that may use it.
EDIT: I glossed entirely over something else quite obvious, too. The vast majority of cabling is Cat 5. 10Gbase-T doesn't run so well on most Cat 5, so something that will allow upgraded bandwidth without requiring changing out of all cables in offices is very desirable.
