If you have typed for years, even with your notsogood method of using only two fingers, you should have some basic muscle memory of where the certain keys lie.
So if you do buckle down and force yourself to get to know the keyboard better using your ten fingers, then you should be on the right track within a couple of weeks.
Personally I think that since you're still very new to the whole typing thing that you should use a more efficient layout than qwerty.
QWERTY was invented to be a slightly inconvenient as typewriters would jam up if one typed to fast.
So I would recommend finding a keyboard that can use a layout like Dvorak or Colemak. You have nothing to lose since you're still inexperienced with touch typing.
Personally, I have been caught up in the qwerty trap and I can't be bothered to get out of it.
Frosty, you're partly right..
Qwerty did indeed have that history you mentioned.
However.. ultimate typing speed is NOT hindered whatsoever by the layout you use..
Sean Wrona, the fastest out there uses qwerty..
and a large part of us who have pushed the speed envelope (125wpm +) notice unanimously that the rate at which we type is hindered by reading and parsing the key combinations for our fingers.
For example.. when I type superserious my fingers parse sup - er - serious I have very good muscle memory for those segments of the word
The more combinations of large strings you've mastered thoroughly, the faster you can type, because it reduces parsing..
for example type asdf, you didn't even have to think about that one, you can do it all day super quick.. that is an example of a string that you've mastered.
now type - gundam - , you probably have to parse that into gun- d- am.. when you hit 125+, this Parsing-barrier becomes difficult to breach..
so in summary.. Don't switch layouts based on the promise that it will be _ultimately_faster_ this is absolutely NOT TRUE, and unfounded..
If you want to switch, you should consider first, whether it'd be practical.. qwerty is available everywhere you go, and already set up.. if you want dvorak, you gotta go into the menu and change it. what if the menu and settings are locked, because this is not your computer.
