I got the wired 1.0 rather than the wireless 1.0+ because of the horrible experience I had with the sigma wireless. This wired unit turns on right away when the wheel turns and I don't think I've missed a single mile the whole time I've had it.
I like that it always shows the temperature, I wished it always showed the clock too, but it's not hard to get to the clock anyway. The altimeter seems to work great, agreeing with the total ascent on several of the large rides I've been on and also being consistent from day to day. The buttons to get to and set functions are very intuitive and I find it really easy to use. I like that the mount has the ability to mount on the stem or the bars and spare mounts are cheap (I have three). Be careful when ordering a mount, if you want a stem mounted one you have to make sure to get that spare mount. They also sell a spare mount that only mounts on the bars. Sadly the only place online I found that sold them was pretty lax about shipping all the parts when I ordered a mount.
Even though I love it, there are of course a few things I would change. First of all, I'd add a backlight, it's a glaring omission in a computer of this price and I miss it on my night rides (I ride with bar mounted lights). I would also change the odometer menu so that it went clock, odo1, odo2, navigator, because I never use the navigator, but if you want, make the navigator come after clock, not before it. The numbers are pretty small, like I said I'd like to show the time all the time, but once you get used to the font and the display reading the numbers isn't that hard, even on a bumpy mountain bike trail. I'm also a bit bummed that I can set the odometer readings but I can't set the total altitude settings for each bike (It has settings for 2 bikes). I've run this over the altimeter counter's max twice now, when it goes over 200,000ft it ends up showing 10's of feet so it will display 250.34 when it means 250,340ft. hitting the all reset button on the back and programming in your wheel sizes, time, home altitude and odometer settings gets you back up and running. It's bit of an inconvenience but you only have to do it once or twice a year if you care.
The sensor wasn't quite large enough to mount on the disk side of my mtb fork, and the magnet that came with it was kind of lame, luckily I had an old sigma one left around to use :)
Cambria is currently selling the VDO MC 1.0 for $100, if it was a bit cheaper I'd buy another one just so I have a spare. Or you could get it direct from the manufacturer for the same price.
I drink a lot of water after a ride and my car doesn't have enough cup holders for them all. I've been keeping my bottles in the pocket behind the drivers seat but they fall over and end up dripping back there and it's a mess. I got 1ft of 3" PVC pipe and cut it into three 4" sections and hot glued them together, this stuck into the seat pocket holds water bottles perfectly. There's more pictures of this in the 
The second ever Santa Cruz Off-Road Metric Century was a huge success! Nicole, Alex, Bob and Dave started off around 8:10AM and 10 miles later we had already spit Nicole out of the back. She broke her 7 year old frame with a clean break on the seat tube. Luckily it had a lifetime warranty, sadly the new front triangle they're putting on will need a new shock :(
Bob crashed on the trail that everyone seems to crash on. Bob's been on some night rides with us in the past and ridden 
In the end by 9PM we did 72 miles and almost 10,000ft climbing. That's over 115Km for those keeping count which means, again, we got 15% extra free on our Metric Century! Having Jun and Char's as a base was as awesome as last year and they were great hosts with a nice spread of food and beer and sausages afterwords! Erin met us after an awesome hike and showed off her impressive blister (should'a ridden bikes!).
