Mac Pro :: Refurbished Vs Configuring New & Subsequent Owner Modifications

I use Macs in a publishing business and have done so since 1986. I have read entries here where one user wants to buy/configure equipment that will last five years or be able to last longer than considered typical. I have read the replies indicating that is not possible, too much change and evolution, buy every 2-3 years, and all that. Since 1986 I have had these models: Mac Plus, IIci, 8600, and most recently a G4 1.25 Ghz MDD. I am writing this post on the G4. It is about eight years old. Look at the number of models I list and do the math. Those are the only machines I have had since 1986. I don't believe I could get this kind of service from an iMac or laptop. Note: The 8600 is still my scanning station, run as required.

What I learn is the computer does what it could do initially as well as it ever could. The problems eventually emerging are multiple. Increasing potential for hardware failure, inability to run newer software as operating systems fall behind, and today, an inability to run the most current browsers due to OS falling behind. I want capability to run newer versions of Photoshop, Illustrator, InDesign, Acrobat, and some CAD or solid modeling software. The G4 is doing what it did initially just as well as it ever did. It just can't move forward...........................
