I'm gonna have to disagree with the majority on this one. While the visual appeal of the logo is great (as usual), you seem to have compromised that for readability. When I first looked at the logo, I had no idea what it said. Then, after reading the title that it was indeed "xthermal", I still had a hard time deciphering the end of the word. Looks more like "xtherman" to me. Sorry, but this is someone's LOGO....their representation. If I had a business, I would hate it if people were always mispronouncing it because I agreed on a logotype that was hard to read.
