Smartphones of the time could not drive an Aero like 3D interface
However they could EASILY even in 2002 drive a decent Windows 3.1 / NT / Win98 /Windows 2000 interface. Aero is a mad trip to the other extreme. Best disabled.
I had 9100 and i9200 "smart phones".
Even a 320 x 240 four shade mono LCD with a Z80 can do a reasonable "3D" hinted effect for buttons, icons, scroll bars etc.
