Technology changes quickly. Right now, computers are 32-bit. I need to have a local company to support me after I buy the software. Pick up the phone and make a call. The local dealer is exactly the same distance from you as A-Systems because most technical support is a matter of answering a question or stepping you through a process.
Computer repairs require someone to be close.
Software is not the same. Software questions can be handled immediately without being at your office. Local dealers can be of assistance in the purchasing decision and demonstrating the software. After the sale, most questions are answered over the phone, whether the person helping you is down the block or across the country. Newer software companies have better products.
