"It's a great phone and I fell in love with Maemo 5"5.0 starson by mr_ian
Pros: Maemo is a great OS it's fast and the UI is very elegant. I'm seeing lots of development and new apps are being added as I write this review. Web browsing is great it's like viewing the webpage on the PC.
Cons: Some feature lack like arranging the application screen window but from what i've read on the blogs these are to be added soon.
Summary: I suggest the N900 or any other maemo 5 device which will be released to all the tech junkies out there. Maemo is a full linux distro and the things you can accomplish with it are great.
