Touch typing isn't all it's cracked up to be IMO, sure if you are a great typist then it makes a big difference but many people can get by just fine without it. I learnt to type at a young age (on a typewriter, which was actually pretty good for training accuracy because if you ****ed up there was none of this backspace cheating, you were reaching for the tippex!) but I've never reached 'pro' level and only do about 60wpm if I want to retain accuracy. Interestingly because I learnt on a typewriter and my first computer was an Amstrad CPC I learnt to always use the numbers along the top even if I'm doing numeric data entry, when the numpad is much more efficient for that.
Even then despite having had formal training I still don't do everything by the book; you are supposed to 'cross shift' (dunno the proper term) i.e. if you are pressing a key with your left hand you are supposed to hold down shift with your right hand and vice-versa, but I don't always do that.
Back in the day as a kid I developed a very rapid variant of the two finger style, except that I also used other fingers for the keys on the edges (e.g. 'A') so that my hands remained fairly central in general. I still think that method was perfectly acceptable for general use but obviously due to training I moved on to touchtyping by about 1990.
