Mobile “Phone” Bill

I was flicking through my mail this evening and noticed that my mobile "phone" bill was split up almost equally between voice, mobile internet and SMS charges. Well, not quite equally - I spend the most on SMS texts (140 messages sent...damn Twitter) and then slightly less on 4.6mb of data. Two hours plus of voice charges made up the rest of the bill.

Two questions:

1. Is this thing still a phone if I spend most of my money on non-voice services? If you add the hours spent using the iPod then the actual "phone" usage probably approaches zero.
2. When are the operators going to start realising this and start pricing data at remotely reasonable rates? Let's be serious - 5mb is just a couple of page loads a day but it costs me more than 2 hours worth of calls.
