first: its and android phone not droid
.... and just in case you dont know:
-you can access the android market via de web
-your purchase are linked to your google account
-you might see some bugs, but looks like the are going taken care of
-i would recommend you to choose to link or keep you data with google, that will a safe back up for you contacts info, and some other info as well, so next time you get a new phone, you just put your sim card and your contacts will appear magically
-remember this is android, if there something you dont like, chances are there always a replacement.. launcher, contacts, camera app.. etc... even the offical facebook and twitter have "optional apps" (third party).
-theres a music/video section int he android market
coming from ios you might not be used to, they are very useful
well thats it for now, feel free to ask questions!
@outatime... he said GSM.. so im not agreeing with you on the charger/battery life issue.. my GSM Galaxy Nexus goes though a normal day of usage with no problem.. that is with constant twiter/google+/facebook use, lots of sms, some internet/market browsing and at least two calls a day... and to that you can add that my google listen checks for update once a day, same as google currents and my grooveip is on all day.
^in that regards.. if you feel like your battery is draining to fast.. drop down you notification tray, tap on the setting icon, then tap on battery... there you will see how you battery has been used.. also check in data usage under setting.. there you can see how your data has been used
