Apple is getting these Haswell chips, AMD graphics, and 8GB (iMac!) RAM dirt cheap. Broadwell is coming out very soon, and Skylake, what people should be waiting for - if they can, this fall.
Force Touch is not a reason to jump. You will practically not even notice it. People, it's just a simulated click.
Broadwell, better battery life and a speed bump will ship next month.
Today's pricing is to move these out. Don't be fooled by a stupid "click" in the trackpad.
You're extremely confused if you think the ForceTouch trackpad is nothing more than a simulated click on the trackpad. That's like saying rumble on a game controller or vibrations on a cell phone are nothing. It's programmable tactile feedback. This is going to be a pretty big part of games, if nothing else.
Further, it can measure force. I'm planning on this being an integral part of a program I'm making right now (it's a music composition program - force will be translated to volume. I can think of numerous other ways that measuring force will allow for quicker and more intuitive controls that existing alternatives.)
