I like the simplicity of #27 and the angularity. If there was an 'M' in the device it would be a contender. The attempt at windows colors in #28 is interesting. The curves are not a fit. Please try using the angularity of the number '7', specifically the 7 symbol from Windows.
Thanks for #37. The blue M could use thinner joints at the top; more 'IVI' and less 'I V I'. Could we try without gradient? Maybe with 'igrate7' to the right if it looks reasonable?
#38 is really interesting. The symbol is a little too abstract and almost too visually rich. It could be made a little more explicit; both the M and 7 take too long to recognize.
Please use white background for further concepts. This will be more appropriate for our website and software. Also, we are eliminating the slogan, 'user migration software'.
Can we please get #70 on white background, text capitalization at your discretion? Ideally the symbol and text will each be usable in isolation. Thanks
