The snap is tough since it is a non-touch device. WM in general has no central directory of "apps" like other smartphone vendors do. Microsoft tried to make one with their marketplace, but it never caught on.
There are TONS of great WinMo apps out there, tho... you just have to actually do some additional legwork to find them.
It doesn't help that the non-touchscreen versions are being phased out and not very popular to begin with (a shame, I really enjoyed that form factor!).
Good luck!
