So, I recently bought a 10.5 Pro wifi model. Still within the return period and I'm considering doing the upgrade to the LTE model. Do LTE model owners feel that it's worth the extra cost? Not only up front but also month to month. (i have one of those AT&T unlimited plans and adding an iPad costs $10 or $20 extra a month to the plan) I've read a lot about the convenience of having always on internet on the iPad... currently I use my iPad out and about I usually have my phone and recent updates have made tethering super simple. I guess the downside is the extra step of connecting to the phone in the settings and also that the battery on the phone will drain faster. Still, not sure if that's worth $130 plus the monthly fee... Is there anything else I'm missing? So far I'm leaning towards keeping my wifi model, but maybe there's something I haven't considered that will push me over to the LTE side.
