OS128XL

Ok, I'm totally lost with all these JJOS versions. I'm still on OS1, but i have OS2 installed, now there is a new one that I don't really see the benefit other than a larger screen. As much as I try to understand JJ's English, its like the bible...I read it, but don't really understand ish. Can someone tell me in simple English what the benefits are? What can it do that my OS1 can't do? $185 for the screen and another $98 for the os...Why do you need it?
I'm just asking the question because I honestly don't know. I'm not trying to knock anyone that wants what they want, but if I spend almost $300 on an MPC that I've already been using, it better be able to do something really fuggin special, like update the effects, plus modulate like an SP-404 or include a built in synth.
Keep in mind I'm more of a MPC + Turntable = studio kinda guy. I'm not technical with a bunch of gear that need to be synchronized. I'm into that dirtball ish. How will spending $300 benefit someone like me?

ike update the effects, plus modulate like an SP-404 or include a built in synth.

it's nothing like that. all jjos's, from os2 on, are basically improvements to the sampling engine, sequencer, and workflow.

128xlcd is just an interesting turn of events, keep an eye on the videos and see if anything catches your attention.

Each version of JJOS is kind of its own world. If OS1 works for you then I would say stick with it. The main benefit of later versions for a traditional sample chopper is non-destructive chopping. Other than that and a bunch of workflow enhancements (some of which are already in OS1), it's a bunch of new features that you will either ignore or realize you always wanted/needed. The new os128xl with the big screen is just the next iteration. It's up to you to determine how you feel about the benefit/cost ratio.

Thanks for the responses and I'll be looking out for those videos. I thought I was missing out on the full potential of the 2500. OS1 does everything I need, but I'd still like to see what OS128XL can really do.
