Consulting the Oracle - mobile phones

[mingmerciless]

Bird entrails etc optional.

My mother's looking for a new phone. Her requirements are broadly as follows:

• Will be predominantly for basic talk and text
  
• She's keen on a touchscreen device
  
• Good UI - she's also been exclusively a Nokia user to date
  
• Not too complex - she views phones like my N97 or my sister's iPhone as over-sophisticated/complicated
  
• Not too big - again, she thinks my N97 is a bit on the chunky side
  

So, anyone know of a mobile which meets the above reqs?
