That's just Nokia's icon grid. Later versions of Symbian also look like that. Meebo (and the Nokia N9) was great, but it wasn't amazing. Honestly I doubt they would have sold enough units to create a reasonable ecosystem anyway, so it would have still been a dying platform, just one where hundreds of millions of marketing dollars had been spent.

At the time when the N9 came out, people just weren't interested in the N9 at all (and this is in Australia, where Nokias used to be best-regarded manufacturer). They had a few disasters with Symbian (the n97/n97 mini/C3/N8), and even Nokia die-hards weren't prepared to recontract with another Nokia handset (I was working in telco at the time).
