Depends on your trails. I wouldn't do anything other than rails-to-trails or urban path type riding on the cdale with the stock 28mm tires, but you could always run some 35mm low-profile knobbies and that would be fine for light XC/cyclocross conditions. Make sure you check the clearance under the fork crown for bigger tires - that is the limiting factor.
As for alternatives, just about any cyclocross bike will fit the bill nicely as a moderate trail/fast commuter bike. I had a spec Tricross which I absolutely loved and was surprised at its offroad ability. Also, look at the Surly cross-check.
