The part of Dan L.'s answer that the Samsung Montage screen size is 1.4" is apparently based on incorrect information on the Virgin Mobile website.
The Samsung website shows both the Montage & the M575 have 2.4" screens. The Montage does, in fact, have a 2.4" screen.

Both have 2MP camera/camcorder, expandable memory to 32GB (microSD card not included), slide-out keyboard, threaded text messaging, Bluetooth and more.
The Samsung Montage lacks GPS, 2G data speeds, has a 1.4" QVGA screen, and is Wireless Emergency Alert Capable
The Samsung M575 has GPS, has 3G, has a 2.4" screen, but is not Wireless Emergency Alert Capable,
