Most of the ergonomic keyboards now aren't split, they are just angled and curved differently. But I do love my split keyboard. I got it for free a while ago and loved it ever since. Only problem is that I now feel uncomfortable typing on a normal keyboard or my laptop.

Also, don't forget the power of the wand! Wands are great. Send in pet, agony, corruption, SB, then wand if still alive. This way you save some mana. Or since you are a warlock ... leave off the SB, life tap then drain life.
