My Google Nexus One has a broken power button. I'm using **CyanogenMod-7.2.0-passion** on it. I would like to configure **trackball** to turn on my device (after battery died or after changing the SIM or SD card). Are there any ways to configure the **trackball** as the default power switch instead of power switch on top of the phone?

I see trackballs mentioned in the MAME4droid settings, but only a virtual joystick appears when playing. Is there support for emulating trackballs via the touchscreen?

I have Nexus One and the power button stopped working. It's a known issue but I'm not in USA and I can't get it fixed since I got it from there. Is there any way that I could wake it up without using the power button and without rooting the phone?

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.

what's the point of the trackball of the Nexus One and of the analogous devices in other similar phones? (e.g. HTC Desire's optical pointing device). Is there any use case for which the touchscreen is not enough?
