you're going to love it.
I've got the ONE, and the ONE XL-S (which is the older version of what you bought) and I love them.
I've had/used a number of others from other brands, and I really like the tomtom best, especially the free map updates.
When I moved here, I had a finedrive 400, which I really liked, even though its an unheard of brand, but the maps didn't have the 540 on them, and there were no updates available.
