I noticed some lack of responsiveness in the sep.18 23138 cht build compared to my old aug 1 version so I doubled the value from 2710 to 5420 in HKLM>Drivers>TouchPanel>PressureThreshold and everything has been feeling much smoother than ever. I run my own UltraHQ themes which used to bring my imagio to a crawl but the sep 18 build handles them very smoothly.
As for the start menu I like the free ram because I hardly use the start menu anyway and just run on my quicklinks. It'd be great if the next build had Tools, Internet, etc folder shortcut icons like the new HTC shortcuts
