Rusty 8' board, What would this board be best for?

I'm trying to get an inexpensive board to learn on...and was looking for a longboard, but I found this 8' Rusty board for only $85, and was wondering if it would be an ok board to learn on. Its 8 foot long, 22" wide, and has thruster fins. I know this isn't a long board, but do think this board would be ok for learning on? I can paddle and pop up pretty well considering I've only gone out a few times.
I tried looking at Rusty to find a similar surfboard to compare this too, and the only one that looked similarly shaped this size was called the 'desert island' and was said to be an all-purpose board.
