Good survey question Wayno.
I'm easily drawn to new technology, and find myself justifying why I need it, or better still, why I can't live without it!

I'll then ponder it for a while, socialise it with friends, hate it, then love it, then start again.
By this stage...the next bit of technology has been released, and I don't bother! hahaha.
Nah...in all seriousness...I'll look at purchasing new technology generally if:
1. I have a foreseeable need for the increased 'value' it has for my needs and
2. If the new technology is accompanied by efficacy and reliability
