I love my garmin 1030+ for pre planned routes. I still have a quadlock for my phone as backup gps maps. There's been so many times the route has changed or just want to go to the nearest place to eat, bathroom etc.. having a phone with internet access is great.
At my age and eye sight I like the larger screen of the 1030+. If garmin comes out with a bigger bike computer close to the size of new smart phones I would probably buy it even though the 1030+ has been flawless.
