I don't have the 788, I'm just a bystander/audiophile,...
but just by my observation, the 788 has a great sound, and packs a lot of features into a very small package.
Obviously, being so small, etc, there are some drawbacks to the 788. Also, being a cutting edge technological device, it's subject to unexpected failures, having bugs and updates, like any other technology you'll find, these days. I think that just comes with the territory.
The 788 has many complex functions, down in those submenus, that's for sure. You definitely have to be comfortable and happy in the LCD-menu-driven environment, if you're not, then the 788 is not for you.
No doubt, when a technologically based device like the 788 fails, or has problems, your song is more likely to go *poof*, into thin air, a way-more likely a pitfall on digital workstations, than on simple analog recorders.
I'm analog. I would not like the 788, or buy it, but as an audiophile, and having heard one, I know the 788 has pretty astounding sound, especially for such a small box. Other than that, I would not like it, I do not like LCD-menu-driven control environments. The 788 is not for me.
However, having said that, I think that if you were to choose the 788, it's a fair choice, a personal choice, and I do believe you'd be best off getting the compatible CDR drive.
The 788 is a decent product, if you like small, digital workstations. As with any device like the 788, you'll be dealing with updates and bug fixes, and eventually the MKII version will come out, likely making yours obsolete.
That's modern technology, for you.
