I'm 2 or 3 weeks into my attempt at replacing my tablet with an Asus Chromebook Flip, so here's my 2 cents:
If you intend on primarily using the Asus Flip in tablet mode, then don't bother with it. It's a nice feature but it's not as responsive as my tablet...which is a very cheap Samsung Galaxy Tab A. The touchscreen is definitely sluggish and sometimes unresponsive. Touch accuracy definitely seems off compared to my tablet as well. Of course, Asus isn't the only brand out there with touchscreen Chromebooks so perhaps a more expensive one would provide a better tablet experience than this one.
If you want to install a bunch of Android apps on your Chromebook, then make sure you get a 32GB Chromebook. That said, be prepared for apps to not function or display properly on your Chromebook. I'm sure this is something that will be improved over time as devs need to tweak their apps for better compatibility with Chromebooks, but this is all in it's infancy right now so expect the worst and be pleasantly surprised when you find an app that works just as well on Chromebook as it does on your phone or tablet.
If you intend to use Chromebook primarily in laptop mode, then you should be pretty happy with it. The main reason I got tired with my tablet is because I did not enjoy typing on it at all. So emails and messaging and posting comments in Android Central felt like a chore. I missed having a laptop that I could use while lounging on the couch or in my recliner, but I also had no desire to spend upwards of $1000 on a windows laptop or macbook just so I could browse the web and have an easier time typing. Chromebook works just fine for that and at 1/4 of the price.
Like everything, there are pros and there are cons. Just gotta decide what's most important to you and go from there.
