Sure are loads of computers, tablets, earpieces, phones and so on but that's the same IT technological side at The Tech Expo by Harvey Norman but I had discovered other new things there. It ranged from house furnitures mixed with some technology as well as the mosquito trap and the mini-projectors costing $400-700+. Even though the mini projectors are quite tiny, they can be expensive as hell. But do you probably want to buy those projectors so that you can project whatever you want? I may recommend the normal-sized portable projectors for such presentations like that.
And of course, I may have an emergency wish of buying one mosquito trap at any time as needed as those stupid flies have been following me for no reasons.
