18 months ago, a friend of mine on this board sent me 4-1/70 OS disk with a cool X5 logo on it. Three months after that my dealer flashed it with 4-1/71 to give me an "upgrade" and it took away my cool start-up screen.

I have been running on that version for about a year and now I'd like to move back to the X5World logo versionl. I tossed it in; updated the OS, and found that it downrevved me to 4-1/70. I'm OK staying at 4-1/70 as long as:
1) It doesn't cause me any problems; and
2) I'm not missing out on some great feature by being on a version that's 18 months old.

Currently it seems to run fine. Any thoughts on #1 or #2?
