New FireWire S3200 Spec
We'll probably first see S3200 used with storage devices like external hard disks and optical drives. Eventually, they hope it will be adopted by consumer electronics manufacturers and used with home entertainment products. The new spec will let consumers connect HDTVs, set-top boxes and computers via coax cable with distances more than 100 meters.
Even though many motherboards are designed with a FireWire port, all include several USB 2.0 connections. With the huge success of USB and the expensive FireWire royalties, unless consumers see a big advantage like better audio and video performance, I think FireWire S3200 will have difficulty becoming as common as USB. Maybe people will understand that FireWire was specifically designed to be used for high speed streaming data and is ideal for a hard drive moving large chunks of data, like video. USB was originally designed for low bandwidth, low latency peripherals, like mice and keyboards. It allocates data bandwidth in inverse proportion to demand, so for example, mass storage gets whatever's left after mice, keyboards and tablets have had their share.
Here's a little more technical information on the topic. The USB 3.0 spec claims transfer speeds up to 10 times faster than USB 2.0, but the real world throughput of FireWire S3200 and its peer-to-peer technology might be better because of the overhead caused by USB's host/client technology. FireWire uses a double-simplex architecture, so for example, with the original FireWire speed of 400 Mbps, the actual aggregate speed is 800 Mbps. USB 1.0/2.0 uses a half-duplex architecture and 10% of its bandwidth is reserved for host commands. There are more delays inserted between TX and RX packets while the host and target devices' transceivers switch directions, wasting several microseconds each time. However, FireWire S3200 might become irrelevant because USB 3.0 is suppose to be 4.8 Gbps using double-simplex fibre, which is faster than S3200 on raw speed and finally gets rid of USB1/2's half-duplex overhead.

The HD Format War - Be Neutral and Pick Both.
The consumer electronics press likes to make a big deal about the HD format war between HD DVD and Blu-ray. Does anybody really care? Most of my friends don't even seem to know either exists. They seem quite content with their DVDs. I thought their lack of interest was because of the confusion created by the choice of two different systems and apparent changing of alliances from the major movie studios, but most haven't even been paying attention to any of that news.
For those of us that do pay attention, why not just use both formats, especially if you use an HTPC. Back in September I wrote a post about the LG hybrid drive that supports both HD DVD and Blu-ray. Actually, I first wrote about these way back in May, but I was more excited about LG's hybrid drive that could also burn Blu-ray discs. LG also announced that its "Super Blu" BH200 HD DVD / Blu-ray combo player is now available at retailers nationwide for a not so cheap $999.
Well, LG started selling these drives in Japan back in September. They finally showed up in North America toward the third week of October. NCIXUS, a Canadian vendor, was the earliest reliable source. They were offering them for around $275 and they were selling faster than they could get them in stock. For some strange reason they weren't available from US online vendors like Newegg.com and PCAlchemy until a few weeks later and they were priced a little higher at around $300.
Now there seem to be a lot of very satisfied owners who no longer have to worry about which format wins. I will probably join them in the near future. Originally, I was waiting for the drive that included the Blu-ray burning capability. Since the Blu-ray blank media prices are probably going to be prohibitively expensive, I'll probably wait to see if the price of the player-only drive goes down when the burner becomes available. I owned a double layer DVD burner for a long time before the media prices were reasonable. At least you didn't have to pay a premium for those DVD-DL drives. The current pricing for a single 25 GB BD-R disc is around $10 - $17.

HTPC Help, What Happened?
Troy/pcCinema decided to quit his own project. I don't know exactly what happened. You could try reading the thread to see if you can decipher it, but it looks like pcCinema just couldn't continue the project. Maybe his injuries (I think injured back) were more than he could handle. Or some people accused him of being a scammer and using his plan to get some donations so he could buy some hardware. I think the former is probably the real reason. There were a few people who were suspicious from the start and they questioned his motives. He didn't handle the criticism very well and probably helped fuel the fires of doubt. After quiting, it would have made sense for Troy/pcCinema to either return the donations or pass the hardware on to people who were willing to help out with the project. He did neither and instead probably pissed off everyone who trusted him, especially greeniquana and binary64.
Meanwhile, it looked like greeniguana and binary64 were going to continue on without him. If they could get their software to work with any hardware, they could really help a lot of people. If you are interested in what they are doing, just respond to the original thread. They also meet every so often on the IRC chat line called "HTPC Project." I think the irc address is 71.244.119.244:6667. The hostname is irc.htpcprojectchat.com. If you search the thread you can probably find the information you need to contact them.
There was also a guy named "renethx" who provided a lot of really good information about hardware. Troy/pcCinema basically delegated all hardware choices to him because of his impressive knowledge. As it turns out, renethx created his own thread with detailed hardware recommendations. I even used it to help select a few components to upgrade our demo HTPC.
So maybe there is still hope. Between renethx's hardware recommendations and the other guy's software scripts, people can find some very good information and potential setup tools to help them build and setup advanced and stable HTPCs.
