What would get you interested in a techy Facebook page?

Hello fellow Verge fans!

I work for a marketing company in the UK and I'm currently working on a Facebook promotion for a company in the business of electronic components and design.

We have done standard giveaways/prize draws in the past but that doesn't really create any engagement on the page.

My question to you is: What would you like to see on a Facebook page like this? What would get you talking? We are planning on giving away an iPad to one random participant.

I've considered a poll of best gadget of all time or something along those lines? Android vs iOS?

Any ideas would be greatly appreciated! I couldn't think of anyone better than the great community to get some ideas from.
