How can I live without a trackball?

I've been using a Nexus One for the past year and half and am very happy with it as a phone. I am *not*, however, happy with my carrier and so will be trading up very soon. Amongst the current crop of 4G phones, the Nexus S has caught my attention, largely due to its similarity to the Nexus One. One major difference between the two has me concerned, however — I absolutely *love* the trackball on my N1 and am having trouble picturing how I'll be able to use a phone as effectively without one. My main concerns are: 1. Text entry. I tend to edit my emails / text messages / etc. as I write them by jumping back and forth frequently. The trackball makes this very easy to do with great precision. 2. Games. I play a number of puzzle games (Shortyz, Vexed Pro, Andoku, etc.) which all benefit greatly from the "scroll-and-click" interface of the trackball. Does the Nexus S (or Gingerbread) offer anything to fill the holes left by the removal of the trackball? I've [seen mention](http://www.quora.com/Why-did-Google-remove-the-trackball-from-the-Nexus-One-when-designing-the-new-Android-flagship-the-Nexus-S) of a "brand new text-selection paradigm" introduced in Gingerbread, but haven't the faintest idea what that's in reference to. I had been hoping for something like arrow keys on the soft keyboard, but if a setting for them exists, I'm not able to find it.
