What I really liked in TM90 is:
1) Unbelievable zoom range: 40x
2) Amazing wide angle: 28mm (extremely useful)
3) Very small, light and quiet (many reviews of TM900 mentioned fan noise issue)
4) Less than half the price of TM900, yet with almost all same features (especially full manual control of gain & iris, white-balance, and manual focus assist). TM900 has exposure zebra - this is the only extra feature, but it is completely unimportant to me.
5) Low-light reviews of TM90 are very good, I did not find any complaints whatsoever.
With these 5 items it was EXTREMELY hard to justify TM900.
Here are other things I like about TM90 (but they are not different from TM900):
6) 1080p60 @ 28mbps - this immediately eliminates all Canon products, including all their dSLRs and compact cameras.
7) I edit the footage with Sony Vegas, render it with SonyAVC codec at 1080p60 @ 24mpbs, AC3 256kbps audio, then merge the two with tsMuxer in .ts file. I can then playback this file via USB on my blu-ray player (as blu-ray disk does not support 1080p60, but USB does, up to 30mbps). But here is the best part - I can use multiAVCHD program to create AVCHD directory from the .ts file, then just copy&paste it to TM90 and playback the edited footage directly from the camcorder via HDMI cable, with full 1080p60 resolution. Both tsMusxer and multiAVCHD are completely free. Perhaps it is possible to do it with Sony camcorders, but multiAVCHD program specifically supports Panasonic brands only, not Sony.
8) I use external high-quality microphone. Some camcorders require a battery-operated microphone, but it turned out TM90 doesn't. So I don't need to constantly remember to turn the mic on and off, it simply uses the power from the camcorder itself. Though same way is on Sony camcorders, too ("plug-in power"). Not sure about Canon - my HV20 did require a battery.
9) Incredible image stabilization. I was completely blown away when I checked TM90 in a store: at 40x (i.e. 1120mm), the hand-held footage was unbelievably stable. I was totally sold. I think TM90 is simply under-priced.
