I used to have a Logitech G15 v2. The mini display was especially useful whenever I'm using Fraps or playing World of Warcraft. The keyboard died after several faithful years for serving me.

Then I bought a Logitech G110 at RM230 because it has a nice backlight color scheme. (Truth is, I couldn't afford the Logitech G19 despite the fact that I was feeling 'homesick' without a mini display)

One week later.. they released the Logitech G510 at RM 230. The same price as the G110. IT HAS A GAMEPANEL LCD.
