Touchscreen or D-pad is not a decision you're forced to make. It will come naturally instead. Where the small screen won't allow the required level of touch precision, the D-pad will fill in. Five homescreen panes to fill with shortcuts and widgets will do better than the good old Active Standby with alternative setups for business and leisure.
Most importantly though, to even the most old-school of Eseries loyalists, touchscreen will be a fair price to pay for finally upping the screen resolution to acceptable levels.
