The T7500 is an Intel brand processor and can be purchased in a number of locations. As it is an inactive model, the best locations would be used computer stores or any number of online shopping sites such as Amazon or eBay.
The T8100 is based on Intel's newer processor cores, dubbed "Penryn". They feature a smaller 45nm manufacturing process, as opposed to the "Merom" core on the T5xxx/T7xxx series. They also include a new instruction set, SSE-4, but I doubt any software is making much use of that yet. Most notably they do consume less power than their predecessors. So the "reason" why the T7500 is 2.2ghz and T8100 is only 2.1ghz, is that they are from two different processor families, and apparently Intel deems that the advances they put into the new Penryn core, allows them to have the cheapest member of the line running at a lower clockspeed than the T7500. Be it performance or power-saving that is the reason behind it, only Intel (or benchmarks) can tell.
Compared to modern processors that are out today such as any of the Core i* series, hell no. When it was released however, it was a decent processor.
The iMac does video editing better than any Windows PC.
Technically, they are nearly the same. However, if you want to see the differences, I suggest you look at these sites. http://processorfinder.intel.com/details.aspx?sSpec=SLA44 http://processorfinder.intel.com/details.aspx?sSpec=SLAP9
