I have been using the Garmin 890 for the last year and a half and it's pretty easy to read. The 1090 is even bigger so I would imagine the display would be even easier to read. Given the price tag, I am not head over heels for the Garmin. I typically have to run Google Maps and the Garmin at the same time because the Garmin does some goofy stuff. One time it insisted I-10 was completely shut down even though it wasn't and kept trying to detour me, it often doesn't have closed road information compared to Google, and it once even tried to take me under a low clearance bridge. Considering how much they want for the unit, I was expecting it to be a bulletproof solution. Overall it does a decent job of keeping me off roads I shouldn't be on, so I continue to use it for peace of mind.
