For an extra £20 compared against the regular Kindle, the touch is great value. Only downsides are it doesn't ship with a power adapter, only a USB cable for charging.
for an extra £20 against the regular kindle the touch gives ya:
1. touchscreen - much quicker navigation than that god awful d-pad
2. music and audibook support with speakers and 3.5mm audio jack
3. 2x the battery life at 2 months
4. 2x the storage space at 4gb or 3000 books
