I was in kind of in a similar situation here in the states. I've been working full time as a computer/network technician for the last 7 years. After all that time, it's clear to me that there in no future in that path. Computer techs will soon go the way of television repair. Anyone who wants to argue this point, feel free to PM me, I will be happy to politely debate you till the cows get delivered to McDonalds.
Seeing no future, I decided that I had to get back into school. At this point, I'll assume that your considering an EE degree.
I don't think you could pick a more flexible degree at this point in time. First off, a true engineering degree (one that actually involves a lot of math) opens doors that other degrees just don't. If you can survive 3+ semesters of calculus, differential equations, linear algebra, and real analysis; not to mention the physics and electronics classes themselves, you will show yourself as someone who is not only intelligent, but able to learn and adapt to challenging situations. 2nd, as you have noted yourself, there will continue to be a demand for new electronic devices, just wait till city/county/country wide wireless broadband becomes common. As I keep telling friends and family, in 5 years, you won't recognize the world anymore, it will have changed so much.
The great thing about pursuing an engineering degree is that there is so much math, you could easily complete a large portion of the degree at any local university. In my area at least, all the higher level math classes are offered at night, usually 1 night per week, it's very easy to work around a full time job. You will also need classes like chemistry and basic calc based physics, it might be tougher to find these at night.
This part will largely depend on your personal situation. I'm single, once I was almost done with math, I went down to part time at work, moved in with my Aunt Deb, and started looking into financial aid to pay for school. I'll be done with my degree in about 1 to 1.5 years, there is no way I can be any worse off then I was working as a full time computer/network tech.
If your thinking at all of pursuing this kind of career, I have to urge you to follow it through to completion. I know 3 people that have the skills to be EE's and are even doing the work of one, but they are getting paid so much less then they should be. However, they have houses, wives, and kids, so jumping back into schools isn't as easy for them.
If you can swing it, go for it.
