I, too, had an original Droid. Loved it and used it for business and personal. Lots of apps. Started to get quirky, so I researched for quite a while and settled on the Bionic, which I bought using my Verizon update.
The 4g/3g issue is real and I find it interesting and retro to use the airplane mode workaround -- but hey - it works.
The biggest surprise to me was how much work I would have getting my new Bionic cloned to match my screens and apps that were on the original Droid. Literally hours and days getting all the apps, screens, widgets back in familiar territory. I had thought having a gmail-based system would make the transition seamless, but not so. I had Lookout backup enabled, but that didn't seem to help. Biggest hassle was trying to remember some of my usernames and passwords (too many senior moments).
In fact, if someone has a good app to recommend that truly backs up a Droid, I'm all ears. Luckily, I didn't trade in my old handset, so I had the ability to reference the old phone for app names and URLs of my favs.
And for those of us that still speak to humans using smartphones, I must say the voice quality is much better than the original droid.
Still can't figure out why Motorola felt compelled to move the on/off switch to the other side, and juggle the four home buttons. My muscle memory still causes me to hit List instead of Home!
