    Xenarc does not require you to hook the screen up to a regulated 12 volt source, it regulates itself. This is why it comes with a cigarette lighter adaptor to tap into the cars unregulated supply.

    god_of_cpu:

    Thanks. I've updated my post. Sorry for the bad info. I took a look at the Xenarc website today. Looks like the screen features have changed a good bit since I bought mine.

    But if there is no app available and VPC is the only alternative. What can you do.

    We can probably do nothing. Its getting someone else with skills to do it.

    yes, that might have some shred of truth to it if Apple made the VPC software. do you know who makes Virtual PC for Mac? ...Microsoft! so who has to stay competetive here?

    dude, atleast google before you speak.

    Afterthought::
    I might be comparing APPLES to ORagnes (HA) putting a g5 next to a EPIA systemboard.
    apples & oranges... are you honestly comparing the power usage of a $2000+ dual-processor G5 workstation (which outperforms every PC available, including dual-Xeon) to a $150 all-in-one mini-itx motherboard??!

    dual 1.8GHz (minimum) vs. single 1.2GHz (maximum) hmm.. i wonder which one has a higher power consumption and produces more heat.

    next time, instead of typing out your afterthought, use the backspace key. it will save you some embarassment.

    Main reason I'm switching my CarPC to a CarMac? Because it can goto sleep and wake up in 2 sec. As opposed to the 30-60sec it takes for Windows.

    wow i give you props for using a mac.

    Im not a pro at macs(although i remember good times playing prince of persia 1 =p) but i always thought macs were a bad choice to put into cars since it seems to be relatively low choices for parts and size for that matter.(again im not flaming but this is to my knowledge only, which is pretty limited) which i think is why PCs are so much better choices for carputers but that is merely just an opinion.

    btw do you plan to house the case in the trunk?

    anyways looking good and please post some pics when your done! Good luck!

    PC magazine seems to think they're neck-and-neck. Ironically, this URL was retrieved from google.

    Are you people that flaming mad at this apple vs M$ crap that u honestly believe anyone today would but a G5 in their car? Impossible. My god look at it, no way. Every mac carputer would be done with any g4, imac or graphite tower dont matter. The G5 the way it is, and probably anything that would come after todays processors, would run too hot for a carputer and probably involve alot of internal parts to keep it working right, like the G5. A G4 though is perfect, just a MOBO, some IDE cable and the PS, simple.

    Comparing apples to oranges aint right in this sense, G5 vs any mini-itx or the like is crazy. Cost is just an afterthought when u consider everything else hardware specific to each. A G4 is comparable to any P3 or less and maybe even crappy P4s. Cuz when it comes down to it, MP3 playback and everything of that sort does play smoother and more integrated into the core OS than windows.

    Yeah M$ now makes VPC but thats better, instead of connectix asking for the source code, its just there for the taking. The newer and newer VPCs that come out in the future should be much better than ever seen before, but it takes time. BUt in the end NO ONE with a carMac should run VPC, dont be a dork.

    yes, PC Magazine did think that... almost a year ago. that data is comparing the dual 2GHz G5 to a dual 3GHz Xeon. of course that Xeon setup outperforms the G5, it's 1GHz faster x2.

    try comparing the dual 2.5GHz G5 to a comparable dual Xeon setup, like the dual 2.4GHz and the data looks more like this... http://www.barefeats.com/pentium4.html

    the 2.5GHz G5 even keeps up with the 3GHz Xeon.

    Every nerd in the world knows different clock speeds for different Architecture.

    Since the Xeon gets less performance per clock tick than the G5 (and opteron) i.e longer pipe, different type of architecture, a higher clock speed would be required for fairly comparing Xeon's to the G5s.

    One test noted, "In fact, under heavy enough workloads there is virtually no performance difference between a 3.2GHz Xeon and a 2.2GHz Opteron (x48). It isn't until you move to 4-way configurations that AMD's platform architecture begins to flex its muscle."

    Now the Opteron's are different, you're safe to pull the equivalent clock speed and it will be close to fair.

    It's a real shame thats only a 2.0 Opteron in those tests and not the 2.4.. Which as you see the 2.0 closely keeps up with the 2.5 G5 as is. The Opteron is the one thats causes the 2.5 G5 to fold like a delicate house of cards.

    And to think to get all that performance out of the G5 required liquid cooling.

    messy.

    Of course, the real issue here is the claim Apple/IBM holds the grail for fastest PC. This is something that changes all the time, and though IBM did real good with that processor of theirs, and alot of its architecture is most impressive, it didn't ship fast enough to meet it's marketing hype.

    But then again, technology always changes and so does the winner. We know which platform has the most 2nd/3rd party support - the majority has spoken.

    Those that want to not conform to the mold may do so at their whim. It makes no difference to me as I use both.

    xp on any reasonable hardware typicall doesn't take 60 seconds to *boot*. pc's come out of sleep in a matter of seconds as well. they also support hibernate, which os x doesn't.
