Pat,
Right now, there is no plan to get rid of OTS. I love the program. Love the computer. I will be using the 2500 as a backup.
I like the thought of using it as a back up vs another laptop because i can do some different things if i need or want to(not that i know how to use most of the stuff yet).
The other thought is...when building new system that an employee may use...will i feel better giving them a laptop...or a rackmounted digital player?
as far as i can tell now, the 2500 doesn't auto beat match, but will crossfade playlists that are easy to create on the fly.
probably the biggest things that it doesn't have that ots does are history file....past show lists, and(at least not that i know of yet) the ability to quickly change the order of a playlist or drop a new song right into the playlist somewhere.
early pros/cons(remember, i'm a novice with the 2500...anybody else feel free to add or enlighten)
pros
easy to learn basics
rackmount or table top
great sound
lots of effects
easy cue settings
nice BIG timers that show time remaining
professional denon quality designed JUST for DJ's
cons
just the things i mentioned above. and maybe the screen...no doubt, compared to a computer, the screen is small...but it's not bad at all...very well designed...lots of good info. I will gladly put up with a smaller screen if it means less chance of an error...or crash.
