E-M5 sometimes annoys, maybe get an E-M10?

Upon reading your comparison of wake-up times from sleep mode between the E-M5 and E-M10 using various lenses, I checked my own E-M5 and GM1 using a stopwatch app.

My numbers with a selection of lenses set to shortest focal length, starting from power off rather than sleep mode, and going to focus lock:

• E-M5 with Olympus 12-50 or Pan 12-32: about 1.7-1.9 seconds
• GM1 with Olympus 12-50 or Pan 12-32: just under 1 second

• E-M5 with Pan 20mm: about 2-2.2 seconds
• GM1 with Pan 20mm: just under 1 second

• E-M5 with Olympus 75-300: about 3 seconds
• GM1with Olympus 75-300: Just over 1 second

Never really noticed a difference in start-up times between my lenses before, just noticeable sluggishness with my 75-300 on the E-M5 when trying to catch a bird in flight that had caught me by surprise.

Sounds like the E-M10 is in GM1 territory when one accounts for the difference between power off vs. sleep mode, and both a significant improvement over the E-M5. I'm now very interested in how the E-M10 fares with the 75-300 if you or another E-M10 user has one, Henry.

I'm also interested in how it feels to no longer have to take special precautions regarding shutter shock. Is it enough to make the change in cameras? I find myself jacking up ISO to 640 and above on my E-M5 in early morning light to capture landscapes without falling under a shutter speed of 1/200 second, resulting in visible noise when viewed close in. It also rears its head just often enough to be annoying when zoomed out to 300mm (600mm equivalent) for wildlife .

And how do you find the overall handling in comparison? Your general feedback is appreciated; I'll likely wait to see what the E-M5II actually includes by way of upgrades (the E-M1 EVF is of interest) before doing anything, but the E-M10 offers so much for so little it's an attractive option.
