Nokia’s Karoliina Salminen posts an entry in her blog about how it feels like to work with the Nokia 770:

…after being able to use it for some time, I became very convinced, it is cool, fast, great to use and does its work - browsing - very well - even when it was quite slow in our terms (before performance optimizations), boot time was at least a double it is now etc. it was fun to use and I have never wanted to go back using a web browser in a smart phone after that. Nokia 770 connects seamlessly to my phone and downloads pages faster through bluetooth than the phone would do by itself with its own browser and instead of seeing just a little part of the page, I can see full pages with no problems with the 770. And one more thing which is great - it runs Debian Linux, it is based on open platform and if you ever find a bug, you can file the bug with Bugzilla by yourself, we can fix it, and you can even provide a patch if you like.
