I got the razr for christmas. It is my first smart phone and i like it. Not much too complain about besides the battery, but i know that is expected with 4G. Didn't know much about the galaxy nexus when I get the razr, but it seems like that is the phone to get. I feel like the only reason i haven't traded in for the nexus is because "if it ain't broke, don't fix it". but idk...seems like the nexus will be the better phone 1-2 years from now. I have untill jan 15th to decide and would appreciate any input between the two.
Keep the RAZR. It seems like everybody that switches from another phone to the Nexus just complains about it for one reason or another.
But seriously, if you like the RAZR, keep it. I was deciding between the Moto RAZR, the HTC Rezound and the Samsung Galaxy Nexus, and I really liked all of them.
I liked the RAZR the best from a hardware standpoint. After seeing just how much abuse my Motorola Droid was able to take in 2 years, I would have loved another Motorola. But word got out that the bootloader was locked. I was pretty sure it would still get rooted, but I didn't want to support a company that didn't listen to what their customers wanted. I've seen how active the community is for unlocked phones vs locked phones, and it's really the community that makes the phone, especially if you're into hacking around. If you are, you want a phone that is condusive to hacking, and you want a phone that is popular. (It seems that the first one kind of causes the second one). The Motorola Droid forum was explosive right from the start and still is. Motorola Droid X, on the other hand, is lagging behind. It was a long time before a hackish workaround to get custom software to install was worked out, and it's still iffy IMO. A good phone from a hardware standpoint, but it's being held back by Motorola.
The HTC Rezound looked pretty good. HTC was making a name for itself by allowing bootloader unlocks, and I liked the phone on principle. I wanted to wait for Samsung before making a decision. If they delayed it much more, I would have gotten the HTC.
I have two Samsung TVs, and I really like them. A few months back, Samsung made news by donating a couple of their phones to the CyanogenMod community to help them develop. This was a HUGE PR MOVE for them. I saw that and thought "now here's a company I can get behind". I was crossing my fingers and hoping that I would like it when it came out. I did.
So the Nexus came out and I weighed the options. The reviews originally said Non-Removable battery. As it turns out, the back of the case comes off just as easily as any battery door, and the battery is definitely removable - and they had a very inexpensive extended battery available at launch. The reviews mentioned a lack of SD card slot. I was a little bummed, but after reading some comments from a Googler that had insider details on the decision, I was sold. Having 32GB of storage used for both /data and "external" storage was a major plus. Other phones only supported 32GB cards anyway. MTP is still not too well supported, but conceptually it makes a lot more sense than USB Mass Storage, as you don't need to disconnect the phone from the storage to read/write. As it turns out, The Galaxy Nexus supports USB OTG out of the box, so you can get a $5 cable and plug in any SD card, Thumb Drive, or USB Hard Drive you want. I think that is better than an internal SD card!
I was worried the screen would be too big. It is too big, but I'm getting used to it. Quickly. A day or so after getting the GNex, I turned on my old Droid and laughed at how comically small the screen felt.
Having an unlocked bootloader means you will always have root access if you want it. There's not some root exploit that might get closed up later. 1 year down the road when the manufacturer and carrier decide not to support the phone anymore, you aren't S.O.L. So long as the community is still there, you will always have options for updating software to the latest and greatest. Also, having a "Nexus" phone means that updates will come faster than they do for other phones anyway.
