The Lumia is very basic. And if you need just a basic phone for calls, text, and maybe e-mail, you could get one for less than 50 EUR.
There's absolutely no multitasking on the Lumia and the app store doesn't offer many useful apps either (and if they're there, you wouldn't find them in this mess of an app store).
The webbrowser on the Lumia is good. Not really standards-conform, but really fast.
