I was searching around to see if there was any news on MIUI for the X, now that it's likely possible, and I came across this tweet from Trey Motes of MIUI (@TreyMotes):
"DX users stay tuned. As soon as cvpcs drops a beta, I will attempt a MIUI port!"
More awesome news! I know everyone is excited about CM7, and rightfully so, but I'm almost more excited about all of the possibilities the 2nd-init method has opened up. Who knows what else may be coming our way in the future...
I've never run MIUI myself, but like CM7, it has a reputation as one of the premier Android ROMs, so it's definitely got me excited about the prospect of MIUI on the DX.
