Long time Symbian user. And even though I switched to Lumia 920 - still keep my Nokia E7 for international travel. (Hate the locked system in USA).
In my opinion, with FP2, base Symbian is pretty elegant OS. It support multiple home screen (customizable background) which can be populated with shortcuts and widgets. I do not use to much widgets, but some external widgets that i installed are:
- Comingnext (for showing things on calendar - I prefer the look compared to default widget)
- World Clock (I support various world zone - this help for quick check on local time)
The apps are shown in Grid and can be regrouped into folder. If you like the look of folders on iPhone there is an app that can emulate that. There are also apps that can change the name / icon of other apps for further customization.
True, apps selection is sparse. But I mainly use the browser anyway to assess most services. Suggest you install Opera Mini / Mobile instead of using the stock (it's not bad, but I prefer Opera anyway).
Nokia Maps is good as usual. Do load up the internet upfront so you can access it offline.
I like using my E7 together with Nokia PC Suite on my laptop when traveling. It makes it easy to tether the internet connection through USB.
