You're speaking of the comparisons of yesterday's computer with today's. These are minimal changes that add up. If you looked at computers 8 years ago to today the difference is absolutely astounding. But 1 year ago to today? Underwhelming. Making things smaller have a lot of benefits. - Axing analog components allow for smaller, digital components that can contain more capabilities - Lighter weight - Typically better battery life / efficiency. You can fit more battery in it and the signals have less to travel. - Research / betterment of humankind. The more we can shrink things the better, easier and faster we'll be able to use the same type of technology in smaller devices possibly even ones that embed into your body.
