If you havent heard of Swiftkey X and you have an android phone/tablet, you should check it out. The version on the market (2.something) is decent, but the 3.something beta version is just astounding. They added something called "smart space" (as in the space bar) which corrects things such as "thisband.this" to "this and this". You can type entire sentences with typos and no spaces and it'll correct it perfectly -- so much so that I can sometimes text with my eyes closed (though it's a touch-screen) and say exactly what I try to the first time

The beta version's free too (the full version, after a free 1-month trial, is $3) so check it out. here's the beta version:
