Finally got my Nexus One today. It was a close battle between the Nokia N900 and Nexus One to be honest, but I ended up getting the Nexus for several reasons. First of all I like that the device is thiner and weights less. Second reason was the platform – even though both (probably most popular phones atm) are Linux-based, on one hand we have Android with Google and looks like an ever-rising community behind it with most of the apps freely available and on the other hand we have Maemo with a much narrower choice of apps of which only 15% are free.
Anyway, since I use google apps for everything from email, to calendaring, and todo notes, it worked out great for me. Just after you enter your google apps credentials an automated sync is started and you're ready to start using you're phone with all the emails, meetings and notes in a matter of minutes (depending on your connection of course).
There are also a few things that the phone lacks, one of them is the second front camera (that even my now older Nokia 5800 has) – It was pretty neat for video calls over 3g. And the other thing is the hardware keyboard, which the N900 has. The virtual keyboard is okay, but it takes a bit to get used to it. I'm sure it will get much better in time but there is no replacement for a good old hardware keyboard.
So far, everything is running smooth. Seems like I ll be sticking to Android for now.
