Project Fiona is basically a Windows tablet with two massive prongs stuck on the side. Each of those prongs plays host to an analogue stick, four face buttons, and shoulder and trigger buttons.
Fire up a game on Fiona and control the on-screen action by holding those two prongs. We played recent smash-hit Skyrim, and were actually rather impressed by how well it ran, as well as the feel of the controller itself.
The idea is that this tablet will appeal to hardcore gaming nuts who wouldn't be seen dead prodding at an iPad. There's an Intel Core i7 CPU inside, which could put serious drain on the battery.
The compromise is obvious though -- Project Fiona is absolutely massive. The prongs alone mean it'll take up a huge amount of space in your bag, and even the tablet bit itself is really thick. It's also expensive, with Razer tentatively pegging it at $1,000 (£650).
We wonder if Project Fiona is really necessary. There are countless brilliant games for Apple's iPad, and while they might not rely on macro-filled mice or keyboards, they're still a lot of fun.
It's just a concept right now though, so let's see where Project Fiona goes next. Razer says it could be on sale by the end of the year, but previous gaming concepts from the company have failed to hit the shops, so we're not holding our breath.
