When I was younger, I adopted new technology as soon as I could save up the pennies to buy it. It was exciting to be using the latest tech and there were often big advancements with each iteration (early sound and graphics cards spring to mind). Twenty years or so on, I wouldn't say I'm reluctant to change, but I move forward at a much steadier pace. Maybe it's just seeing things through an older and more cynical pair of eyes, but I do not think there are as big advancements in new products today as marketeers would have you believe.
In everyday life and work, I generally use what I know well and does the job well. Operating systems, utilities, hardware, etc; I'm in no rush to upgrade or change them unless what I'm using now becomes unsupported, deficient in some way, or there are very real benefits to making a change. That kind of approach has served me well; my systems are robust, efficient, and I know the insides well enough that I can fix things if and when they go wrong.
For fun though, and to keep on top of emerging technologies, I do 'play' with a lot of new stuff when I have the chance. Test new operating systems, software, etc, in virtual machines. Evaluate new hardware if you can get your hands on it cheaply or for free (on loan, in store, or from friends). That way, you're always going to be aware of what the choices are and you'll be continuously building a picture of where technology is moving, and whether it's something you should think about adopting for yourself.
So, be careful to not get stuck in a rut and set in your ways, but don't rush out and buy every latest widget for widget's sake.
