I have been using Apple since 84 and this computer is the worst I have owned ( I have 9 including notebooks and desktops)

This model, 1.8Hz dual was the most expensive and is fantastic when it works however it suffers from the fact it has a Chinese produced main board which has been known for years to become faulty.

ALL my other computers still work, not the G5! Apple appears to have ignored this problem and changed only those under warranty. The price of a new new board out weighs the value of the computer and does not make it economical to replace. This is diabolical from a quality computer company such as Apple!

I have owned a dual 2.5mHz Apple Power Mac G5 since July 2004. It has saved my life. I am a teacher and need a rapid and reliable machine: it has never crashed. It was expensive to buy (even with educational discount) - I part justified the cost by setting it up as a TV to.
I have a disability and would say that I am reliant on this machine for many of the vital things in my life - communication and shopping. It's accessability features are very impressive.
I understand that the machine has now been updated with a version with dual core chips - making it even better.

I have had this Apple Power Mac G5 computer for over a year now and I have only good things to say. It is fast, stable, runs cool thanks to all the fans and the hardware in it is top notch. I have later upgraded with an airport express card and second 250 GB HD. I needed to replace the motherboard after about 6 months. I was not very happy about that, but it was within warranty, so a Mac shop took care of that for me. People also compliment on how it doesn't look as boring as most other computers.

In my humble opinion the Apple PowerMac G5 is the daddy of all computers. Had mine a couple of months now and really could not be happier. It's not as quiet as I was led to believe but that's a small complaint as my music hides it anyway. It is reputed to be the fastest computer in the world, and it certainly is rapid, no complaints in that department. Buy one or settle for second best...

Apple Power Mac G5 - This is a superbly engineered computer, I've never seen build quality this good before, it's a perfect example of form and function which just oozes class. The operating system is the most robust I've ever used, I've had mine over 6 months now and IT'S NEVER CRASHED! If you're a serious PC app user on a budget look at a cheap and cheerful Dell, otherwise make the switch to Apple, you won't regret it!

I don't own one of these computer systems, but I use them a lot.
I'm studying Music Technology in my first year at University and we have 8 of these Apple Power Macintosh G5 1.6GHz babies!
When I started my course, I'd never even touched a mac but I fell in love with the OS.
I've been a Microsoft user for 10+ years but occasionally used Linux.

Anyway, the OS is slim and smoothline, everything runs like a dream. Originally using 10.2.8 but then switched to 10.3 when it came out. OS 10.3 is soooo much nicer again!

As there's a 64bit processor, a lot of programs are not 100% compatible with it, but more are coming out. There's a lot of freeware, especially as you can use Linux based applications with it (built in X11) albeit with a little bit of tweaking.

Anyway, my overall feeling is WOOOW :)

I bought one of these Apple Power Macintosh G5 1.6GHz Computer Systems over five months ago.
In my opinion this machine is vastly over rated and overpriced.
Apple have been very measly with the input and output ports, for the facilities you have available to you the size of the unit is far too large and with its numerous fans it is far too noisy, but thats what you pay for ! "big bucks for big bangs."
the machine works well with the software that is available for it, if you can afford it !!

The long-awaited Apple Power Macintosh G5 1.6GHz is out. Having test driven the 1.6GHz it is marvellous. It really is very quick and outperforms a G4/1.25GHz visibly. This is really the machine OSX was made for. Installations and shutdowns are far faster and with the reliability of IBM processors hopes for the future of the G5 are high. I was disappointed that it only takes 1 further serial ATA drive but with the cost of FW drives it doesn't really matter that much. With it being a 64 bit processor the memory required is in pairs and the G5 takes up to 8GB which should be enough for anyone for the next couple of years. I would like to get my hands on the dual processor 2GHz model which is a good sign. I have tried to fault it and throw SW stuff at it but I can't but have the impression that this is a serious machine that lives up to the high expectations of what it should do. Sure it's large but you get used to it and it does grow on you.
