I installed Binky’s 3.4 ROM today.
Comparing this install to the K’s Rom 1.31 Lite I had previously on the device, it looks better. More memory available for program and Storage.
Storage: Total 70.98MB, in use 3.07MB, Free 67.91. Program:Total: 48.68, In use: 21.48, Free: 27.2MB.
After installing Point UI 1.51a,
Storage: Total 70.98MB, in use 5.28MB, Free 65.70. Program:Total: 48.68, In use: 24.52, Free: 24.16MB.
So after PointUI installed and running, I am only loosing 3MB. Much better then the 6MB lost in my last setup.

So far, both PointUI (with the PointUI optimized font rendering on) is much much faster. Also (I guess due to WM6.1) applications take less time to launch.
Overall, certainly an improvement.
