"A Mac is begining to be a PC anyway, so why bother buying a Mac...So if you are buying a Mac to run XP or Vista I don't see the point to get one, buy directly a PC instead of hybrid computer called Mac"
My point is, if he wants to do basic video editing, get the Mac because it comes with it. If you get a PC, you have to also buy video editing software. In other words, get the Mac and only buy graphics software, or spend more money on a comparable PC, then buy BOTH the video editing software AND the graphics software. Getting the Mac saves money in this case because you're NOT buying it just to run XP or Vista. You're buying it to run OS X, XP, Vista and/or Linux. It's by far the most flexible solution.
"The concept of PC is buying the best parts on the market not necessary the same brand, that's the philosophy of PC enthusiast. There are many conponents you cannot install on Mac."
What can't you install on a Mac? Name one component and I'll send you a link to where you can get it for a Mac. And do you really think Apple makes every component that goes into a Mac? The video cards have always been either ATI or nVidia, straight from ATI or nVidia...not some 3rd party. The hard drives are Seagate, Western Digital, IBM, etc...all name brands and top of the line. The optical drives are top of the line Plextor, Panasonic, Pioneer or Sony. For that matter, from OS X 10.4 on, you can install pretty much any brand of optical drive and it boots, burns, etc. I've got a Lite-On DVD/CD-RW Combo drive in one of my old G4s and it works like a charm. Apple owns Firewire, so they get the best of the FW400 and FW800. Why do you think Macs have been given the reputation of being more expensive? (Not actually the case when you see what really goes into them.) It's because they only use the best high-end components.
"Whatever memory RAM you've got, the only existing memory Ram is 2GB so if you've got an average MB with 4 slots, you cannot put more than 8GB."
The Mac Pro I talked about earlier can take 8, 4GB sticks of memory (yes, there is such a thing as a 4GB memory module and the Mac Pros have 8 memory slots). Thereby bringing it to 32GB.
"Back to the topic, PC or Mac it is just a personal choice for business, as you mentionned you can run every softwares on high end Mac with OS X, XP or VISTA."
You don't have to have a high end Mac to run Windows XP and Vista. I have a very LOW end Mac compared to what you get now and I can run both Windows XP AND Vista. For that matter, I can triple boot between OS X, XP and Vista if I really wanted to install Microsoft's latest bug (talking about Vista). Windows XP runs better on my low end Mac than it does on most of the PCs I've used.
So basically, if you want to literally be able to do anything on Mac you can do on Windows, now you can.
It definitely comes down to personal preference. I tend to want to do more while spending less. That's why I have a Mac Mini and not a Mac AND a PC.
As far as porting OS X to PCs...never going to happen. Here's the reasoning: Apple is a hardware company. Everybody hears about the iPod this and the iPhone that, but by far, the majority of their sales comes from computers. It doesn't make sense for them to start making their OS run on other people's hardware because then they wouldn't sell the hardware. That would kill their business.
Now, while it doesn't make sense for them to make OS X run on other hardware, it does make sense for them to make their hardware run other OSs. The more flexibility you can have with what your hardware will do, the more likely people will buy it. For years the argument has been that people love Macs, but they wouldn't buy them because they couldn't run their Windows programs. Now that Macs will run Windows natively, that argument goes out the window. It's one less roadblock and their market share has risen because of doing things like that.
Let's throw something else into the mix. Say you're Bluesuit and either you've built your own PC or had someone else do it and your video card goes out. What do you do? If you're not ultra-experienced with this sort of thing that can be a nightmare. Who does he call? Geek Squad most likely. And because they didn't sell him the computer, they charge him to bring it to them to fix it. So he's paid for the repair AND the new video card. If he's got a Mac, he takes it to the Apple store and they fix it for free (assuming it's under warranty). Doesn't matter what hardware he's got, anything goes out, they fix it.
Here's a better example...the power supply goes out. If you have a PC, you buy a new power supply. That still doesn't work because the bad power supply has fried your motherboard. So you buy a new motherboard, but that still doesn't work, because the bad motherboard has in turn fried your CPU. So now you buy a new CPU which also doesn't work because the bad CPU fried the new motherboard you just bought. That's a real situation I had to go through a few years back. Good luck trying to get any kind of warranty work done for your OEM stuff. I ended up having to eat the cost of a motherboard and CPU. If a power supply goes out on a Mac under warranty, you take it in and they fix it for free.
I can't believe I got suckered into this PC vs. Mac debate. All I was trying to do was help this guy save some money. I know both platforms inside and out, so I know exactly what I'm talking about. I've been working with Macs for 20 years and PCs for 15. I build them, fix them, upgrade them and sell them. Always before, when people would ask me what they should get, Mac or PC, I'd ask them what they were needing it for. The vast majority of the time I'd recommend getting a PC because of the software they wanted to use. Now that Apple has decided to have their hardware run Windows also, that's not always the case.
So, as far as I'm concerned, I'm done with this topic. I can't explain it any better than I already have and it's so far off its original base it's not funny. Some people you're never going to get through to no matter how clear you make it. I just hope I've helped Bluesuit with his question. As far as I can tell, he's not a "PC enthusiast" as you say. He's someone who wants to do more while spending less money with as little hassle as possible.
In closing, it's okay if you love your PC and you hate Macs. Stick with your PC. But don't try to sway someone else's decision when you don't have all the facts.
