txt msg nvl: "The Last Messages"

A new novel by Finnish author Hannu Luntiala is written entirely in txt msg lingo. Released this month, the novel The Last Messages tells the story of a man who quits his job as an Executive and subsequently travels through-out Europe and India, keeping in touch w/ friends and fam by IM-ing on his mobile.
The 322-page novel --a quest? a techno-picaresque? shorthand epistolary?-- lists his messages and the replies (about 1000 altogether) in chronological order.

I've seen a few novels that make use of e-mail exchanges to tell the story, but this is quite an endeavour, for both the author and the intended reader. I'm behind the idea from a creative standpoint, but do I really want to read 322 pages of txt msgs, complete with broken grammar and slang? Does it make a difference that the messages are fictitious and therefore I can expect some sort of compelling plot? (Is that what I expect when I read a narratve?).

The novel makes me think of Kenneth Goldsmith's Soliloquy, in which he transcribed every word he uttered for a week while living in NYC. It's a real-time monologue, an extended aside.

Which would you rather read? The Last Messages is a creative work that exploits contemporary technology and trends, Soliloquy is an "uncreative" artistic mirror held up to the idea of the monologue, the constructed narrative-reveal. It is pure doumentation. What do the different methods, fecund creativity or "nutritionless" uncreativity, offer? Could you tell the difference between a constructed narrative made to look like documentation, and an actual documented life that resists the tropes of dramatic monologue while still investing in them?

**"nutritionless documentation", and "uncreativity" are terms Goldsmith has used to describe his work.
