The N9 is still a very good phone by today's standards. I'm sure you'll like it. I have a 16GB one and that has been big enough for me.

Some of the actions take a minute or two to get used to ( the swipe across to change between apps and the swipe down to close) and some of the nifty features are not immediately obvious.

For an OS that has only had one update it is very mature, is very stable and very well featured. Much better than WP. The phone comes with Swype preinstalled, along with Skype and a host of other apps. It has a very good document reader, BUT doesn't have any document creation or editing software ala QuickOffice etc.

The camera is very good and as already mentioned the Maps and Drive apps on their own make the phone very worthwhile.

For me there are only two things I miss on the N9, a keyboard like the E7 or N950 have, and document editng software. Otherwise it's perfect.
