Drop it. Or rather evaluate how long it would take you to catch up with them (in their existing state) including the hardware part - acquiring it, stocking, selling, supporting, etc - and then see if you are willing to do that knowing that you will also need to out-market them. Then sit down and think about it. Realistically you are too late and you are too few. Think about it a bit more and then drop it.
