Truly miss voice dialing capability, but I have found that Super Contacts Plus (in app catalogue) kills two birds with one stone.
First, it's a photo-dialer (set it to only show text for people who don't have a picture, or the text covers the pic)...
Second, it gives you the ability to group contacts - something else I really miss from my Centro. Make lots of groups, with not too many people in each and you won't have to scroll through a lot. Multiple taps on any picture brings you to different contact numbers (and sms, email options) for each person - and there's a quick launch bar too, as a bonus.
Not voice dialing, but safer than trying to look someone up, especially while driving - and faster, more convenient in general. Love having my groups back for hard to find numbers where I can't remember the name (who was that guy that drained my septic tank two years ago?? He's listed in the "Trades" group...)
Go for the Plus version rather than free - more options, unlimited contacts.
