Here is a good overview of early PCs - http://www.blinkenlights.com/pc.shtml I'd say the Altair was the first computer that an average person could purchase and use. It was a hobbiest machine, but at $600 it was more affordable than the IBM 5100 at $10,000 plus.
Personal computers (PCs) became widely available in the early 1980s, with the release of models like the IBM PC in 1981 and the Apple Macintosh in 1984. These models, along with the rise of compatible software and peripherals, contributed to the growing popularity of PCs in homes and businesses. By the mid-1980s, PCs had become a common fixture in many households.
The Power Mac G4 is one of a series of personal computers that had been designed, made and sold by Apple from the year 1999 to the year 2004. These series of Mac computers were once considered to be the first super computers according to information available on the internet.
Computers have been out for many years. In fact the first electronic computers were punch card devices that where extremely massive, the size of large rooms with massive power requirements to do simple calculations. The "home" or "personal" computer came out in the early to mid 1970's when the Microchip (integrated circuit) became more widely available. Systems such as the IBM System/32 and The Altair were the first in the line of these products.
4G is becoming widely available throughout the year, so I would expect it to become available soon in the Northwest as well. It is becoming very popular so I would expect a year or two.
HP released the first Jornada PC in the year of 1998. Many more Jornada personal computers were manufactured until the year 2007 when they were discontinued.
