I'm odd duck out. TomTom owner here for years.
I wanted the 'biggest' screen I could find and I wanted text to speech for 'inputting' directions. I didn't want to hunt and peck to input my route. You only have to push one or two keys as she asks where you want to go and you just verbally answer.
At the time the only GPS that filled this bill was the TomTom.
After 6 years I am still using the same GPS and like every single thing about it!
I just keep reading a lot of posts here on the forum that the lower cost Garmins are almost expected to die after a year or two necessitating purchasing another one often.
