I've has my Galaxy Nexus for almost a day now, on Three UK.
I hate how most people rave about phones when they have just forked out for them, and fail to mention any real negatives. When you buy one and it's missing features, it's very annoying than no-one mentioned it.
Here's my thoughts so far. I consider myself a power-user, and have tested almost everything. Overall, people are right. This is the best phone I've touched. I think once devs start making their apps work properly on ICS it'll be much better. Fingers crossed that Cyanogen will fix lots of the annoyances below.
I hope this is useful for someone
Feels much more complete and unified.
It's lightening fast.
Most of the best bits of Android have transferred.
Screen looks great.
Face unlock works much better than I thought. Even in low light.
I've only had one crash despite installing a tonne of apps and testing every feature. [EDIT: loads of FCs today. Stay away from the pre-installed Google Earth).
Radio seems to work fine on Three UK, unlike the SGS II which has data issues due to fast dormancy. Data speeds are great.
Browser generally much better.
Text input much better, but editing is a little confusing and seems to vary depending on app.
Screen size is great for me, as I use my phones as mini-tablets. Doesn't feel bulky in my pocket at all.
BLUETOOTH STEREO FINALLY DOESN'T DISTORT
- I can hear hi-hats again instead of just distortion. There is a bit of constant crackling though.
Screen remains responsive when charging. I have had an issue where it wasn't registering touch properly when charging on my Milestone, Desire and SGSII so this is really nice.
The 'menu' button is unpredictable. For example, in most apps it appears at the bottom with the softkeys. In Market it's up at the top, near the search button. In some apps, it has gone. Seems to vary and is confusing.
You're stuck with the Google search box on you home screen. I hate this.
Now the button has gone, if an app doesn't have a search icon, you've lost the ability to search.
Also means no long press search, so you have to go back to the home screen for voice commands. This also means that regardless of what launcher you use, if you want voice search, you NEED to have the Google search widget on your home screen.
No USB Mass Storage – they've opted for media device profile instead. My Xbox recognises it but can't play any content. It doesn't work with my car stereo. It doesn't work with my TV. My laptop will see it, but I can't see certain hidden folders. This has just removed a huge aspect of flexibility from Android. It's no longer universal, and more like an iPhone now in that respect.
Icons are as ugly in real life as everyone expected.
Blue theme clashes with everything except blue. Blue icons on blue background feels very bland.
Speech to text seems to dislike my English accent, whereas the old version worked fine.
No longer accepts certain file formats over Bluetooth.
Camera seems buggy when reviewing photos. It works confusingly.
Gallery is not very intuitive at all.
Dropped a few calls.
Wifi range isn't as good as my other Androids
Front facing camera doesn't aim inwards towards your face. It points straight forward at 90 degrees, but it's positioned on the right of the device, so your face isn't central unless you hold the phone at a bit of an angle facing away from you. [EDIT - this is getting very annoying now. You have to have the phone scren pointing almost away from you to video call]
Bluetooth calls don't seem to work. Caller can't hear what I'm saying.
Bluetooth music has a constant crackling behind it, but it's barely noticeable in loud music.
All albumart appears in the phone gallery.
Apps - If you can't live without these, I'd recommend waiting to buy until they're fixed
No menu button is shown on Facebook, so there's no way to set it up to sync contacts or notifications. This means no contact photos for now.
Twitter on the other hand syncs all my contacts, despite me telling it not to.
Doesn't support Swype as yet.
Doesn't support MX Video Player.
iPlayer not available in the Market.
