Something which isn't on there is Windows. Despite the rut Microsoft has been in the past few years and their flat out refusal to offer a new version of Windows from the ground up, instead offering just face lifted versions of version 6, eventually Balmer will get the boot and a new innovative CEO will be put in. Other things not on the list that I think we will still be using are:
1) DRAM. Yes there are faster competing technologies, but given the fact that aside from the chips inside APUs, nothing the home user has really benefits for anything faster than DDR3 1600. Of course, DRAM is also cheap as dirt. Sure there will be DDR4 and DDR5 and so on, but those will primarily deal with lower voltages and higher densities, as well as lower costs (die shrinks).
2) NAND based flash SSDs. Yes there are faster and longer lasting technologies set to replace NAND flash, but as their capacities and speeds increase and their costs decrease, they should replace HDDs completely by 2030 as internal drives, with massive HDDs (5TB or larger) serving as backup drives, similar to the way tapes and ZIP disks did.
3) Plasma displays. Yes, those energy hungry, short lasting displays which have been around since the 70s and are banned in some states and countries due to their energy usage (California, for example) I think will refuse to die by then, though I believe LED lit LCD panels will improve in viewing angle enough to replace Plasma in the majority of cases.
4) Mice. Touch will not kill mice just like voice recognition will not replace keyboards.
5) Wrist watches. Despite everyone being tethered to their cell phone, the centuries old wrist watch will still keep on ticking on our wrists for decades to come, at least until the 22nd century if Star Trek is to be believed.
6) Eye glasses. Despite laser eye surgery and specially designed contacts which now give people greater than 20/20 vision, the vast majority of people will still be using fairly inexpensive eye glasses for their vision.
7) Power plugs. Despite the technology having been invented decades ago by Nikola Tesla for wireless power transmission, components will still be tethered to the wall plugs.
8) And finally, the Internal Combustion Engine powered by Gasoline. Sure Hydrogen is the future, no doubt about that, but until people have access to personal hydrogen generators (e.g. a tank of water and an electric current basically) gasoline will continue to be around, because there's a ton of it out there.
