Male, age 55, Working with computers since 1979. I was working on Mainframes when the first PCs came out. The first portable I saw had a 3" x 4" text screen and weighed a hefty 75 lbs. My smartphone is more powerful that this "portable" was. The technology has been changing so fast it is extremely difficult to keep up with all the latest and greatest. PCPP is a great site for building purposes. Incompatabilities are caught before you pay the price.
