The Asha 301 is a classic Nokia, if you've currently got a basic Nokia you'll feel right at home with this handset. It's a good design, should easily fit in your hand, and it has a great keyboard.
The screen is clear, although fairly low resolution (which you expect with a budget handset). The menu is easy to navigate and you get access to a small number of apps. Facebook comes preinstalled so is easy to set up, and you can send/receive email as well.
The predictive text feature is good, and having a camera is a nice bonus at this price.
You can use this as a music player, but theres no volume rockers on the side of the phone so you can't easily adjust the volume.
If you're not fused about loads and loads of apps and just want a simple, classic, handset to talk, text and a bit of internet access, then this is a really good options.
