There are no draw backs when looking to get a computer that using Hyper-Threading. If you do not like the feature you can just simply turn it off. There are many system on the market that claims to be Hyper Threading enabled. Intel has a utility program that checks for Hyper Threading ... 1. You must have the proper CPU's. 2. You must have the proper motherboard. 3. You bios must support it. 4. Your Operating system must support it. Once these things are met your system will indicate that Hyper Threading is enable before booting into the Operating System. It is not an indication that you will see when the computer is turned on and the Bios is posting. Soon all of Intel processcor's will have Hyper Threading. So if what you are using your processor slows down with Hyper Threading, just simply turn it off via the Bios.
