    To me its certainly much more capable then just slimming down a win7 installation on your own (it has some unique components) which is pretty nice. However, I find it wayyy to conservative in its requirements which forces me to add a lot of crap I know my software will never need or use (and I later have to strip it out). I also think there might be some issue with using its mp3 codecs, etc but i'm not 100% sure. As far as availability to the masses, definitely not on its own but certainly in commercial carPC endeavors It's $1000 for a development license and then $99 per individual license after that.

    Pricey. I'm still anxious to see it cold boot.

    8 seconds resume from hibernation is very impressive. What motherboard are you using?

    It's just a jetway board..the big difference is the m4-atx is connected to the usb header for tuning on the fly. It has a 100ms startup delay compared to the usual 2-3seconds. Plus I have a solid state drive and only 1gig of ram in the carPC which takes another second off the resume speed.

    8 seconds is an amazing boot time, even without any PSU delay. How is that split, 3 seconds BIOS POST + 5 seconds OS boot?

    Sounds like this would be AWESOME as a pcie addon card. Like those PCIE hard drive cards. Imagine having the OS run from a card, ha ha. ZOOM!

    That was an 8 second resume not an 8 second boot...so actually the times are reversed. 5 second post...3 second resume.

    This is a cool thread. First all I will say I have always used hibernation and love it. Yes I love the idea of S3, but the power my system eats is huge. So I am wondering, when you use S3, what exactly stays on? My setup will be using a quad core 65W processor, 8GB of ram and 30 USB devices. I can imagine that if USB is always on, the PSU will kill the power in maybe less then 30 minutes. I to plan to avoid the time for hibernation by using a remote starter also.

    How good does Hybrid sleep work, and is there a way to not have all the USB devices stay on?

    uh were to begin.....

    Ok i'll answer the question first-in true s3 nothing should remain powered on except the system RAM. However, any USB device is capable of preventing the bus from powering off and thus keeping all your usb devices powered (although many will be in standby). Theres easy ways to fix that though as long as your aware of it (pwcfg.exe). Obviously it varies by setup but your looking at 30-50mA per stick of RAM.

    Now as far as your setup....not only is it beyond overkill for any carPC application but its going to have serious performance issues. There is absolutely no reason whatsoever to have 8GB of RAM. 2GB will more then cover the needs of even the most bloated quad core setup. The only time 4 or more is needed are for databases, HD photo/video editing and very high performance gaming (doing any of those that we should know about?). Second and most important-your putting the money in all the wrong places if you want a quick startup -> your hard drive is going to be the weak link here.

    Well its only 2 sticks of RAM. I did plan on having gaming avaliable, but that also requires a good GPU and I am using a Geforce 9300 chip set, which is ok for gaming. So your saying i should upgrade to a SSD?
