I got an XE-1 two weeks ago. Used once and then went on a desert trip for four days. Don't sell the X100 for the little you will get. It's priceless IMHO. This camera is destined to be a classic. It was so easy hiking with this camera and the 28mm supp lens. So portable. I just couldn't take the new XE because I wasn't familiar enough with the unit. But carrying the X-100 for 4 days, everywhere, afforded me ultimate portability in a camera that givens fantastic results. Looking forward to getting to know the XE, but won't ever give up the X100. Just one guy's opinion.
