This sounds to me like the sort of situation where you could just let him know how genuinely confused you are (even though you're obviously trying to be a great girlfriend by trying to find out about it in secret), watch his look of fear as he realises that it's very likely that you will not get exactly the right sort of thing he wants, but will instead get something that to you (and to the rest of the world) is pretty much exactly the same but to him (and any other gadget freaks out there) is actually a zillion miles away from what he wants.
He should then be happy to get it himself, and/or tell you to get him something that is easy to get.
It's an unreasonable request, IMHO. It's like a teenager asking you to buy them something fashionable. With the best will in the world, you will get it wrong. Respect to you for trying, but beware of it all ending in tears.
It's be like me asking a work acquaintance to buy me cider. They'd mean well, and I'd have to look extremely pleased when I ended up with some Strongbow.
...if you press it, they will come.
