R&D: IBM's Racetrack Memory, Data Storage At Superfast DRAM Speeds
Racetrack memory, is a new type of magnetic memory that has magnetic domains "racing" along tiny nanometer sized wires, giving performance similar to conventional DRAM. Invented by IBM Fellow, Stuart Parkin, it has been in development since about 2004, with a working prototype having now been unveiled containing 256 "racetrack" cells, each containing a single wire. The technology works by sending very fast electric pulses down these wires, measured in nanoseconds, which transmit very fast moving magnetic domains which are then read by a magnetic head either as a one or a zero, depending on their direction. IBM said in a statement: "This breakthrough could lead to a new type of data-centric computing that allows massive amounts of stored information to be accessed in less than a billionth of a second."
IBM has an article on this technology and in it, they give a very clear and detailed explanation of how this technology works, so we'll let them explain:

IBM Researcher Stuart Parkin pioneered the development at the company's Almaden Research Center in San Jose, California, starting in about 2004. Parkin conceived of a device consisting of a city of skyscrapers-each one only hundreds of atoms wide-of magnetic material, with each floor of each skyscraper containing a single bit of data. The data is shot up and down the skyscrapers-almost like a supersonic elevator-by using special currents of electrons for which the spins of the electrons, a quantum mechanical property, are aligned in the same direction. By passing such "spin polarized" currents through the data, the magnetic data can be moved up and down the skyscrapers which are vertical racetracks. These currents are generated by a transistor connected to the bottom of each skyscraper. "In this way, each transistor can store not just one bit of data, as in all other solid state memory, but rather 100 bits," Parkin said. "This means that one can have a solid state memory with the same low cost of a disk drive but with a performance 10 million times better!"Makes today's expensive "cutting edge", low capacity, limited lifetime and above all, way slower Flash-based SSD's seem so yesterday, doesn't it? One can imagine Windows booting up near-instantaneously with one of these.
A personal storage device using racetrack memory could fit into a lapel pin and record every conversation its wearer has for years before filling up. In enterprises, massive storage could be dispersed, with terabytes of information built into every device, sensor, camera and doorknob.

I've always felt that Microsoft need to tighten up the process as alot of PC gamers are clueless as to how much unwanted services/software can impact the gaming experience.
OS/2 (a full 32 bit OS when microsoft could only offer win 3.11) or linux and ditching CRISC, the world would be a much better place
EDIT: Just to prove a point Vista still loads and runs pretty well if i lower my processors down to 800MHZ, with Vista and 7 processors and graphics mean nothing, it's just RAM and storage speed, and luckily, RAM is dirt cheap
Do you not like that Windows 7 uses more resources to be better? Don't try to prove your point with the bad one that didn't succeed well.
There is of course a balance to be kept, but Windows 7 is fast enough while packing a lot more features then Windows XP
The tech certainly looks promising and I think it's about time we had a breakthrough like this. Think, it has the capability to make for an instant suspend mode on PCs without using power. Currently, the RAM has to be left switched on to make this work.
If it could be made cheap/small enough you could use it like flash for drive-size storage at better than current RAM speeds (connections not withstanding). If there is only one kind of storage needed and massive amounts are produced for external storage use, the price should (in theory) drop.
