Oh, yes! I have a red one which I got in August of last year, as soon as they came out. There is a LightSpeed Addicts Anonymous on www.depoman.com. Search for LightSpeed, and you'll get a number of threads. I also have a blog and a webpage dedicated to my LS, but they are a little out of date. 
I was at the GSRA technology conference last weekend with mine. I met with a student from Brown, and she liked it a lot. The only hurdle you need to clear is, does your school require paper notes? If they do, you can't use the LS because it doesn't have a paper option. If you just have to turn in your note file, you can use the SD card in the writer.
There have been some Eclipse users who have had problems with dropping/scrambled strokes in their realtime, but the strokes are always on the SD card. Again, they are discussing that on depoman, and it looks like it is getting resolved. It appears to me to be a Bluetooth/usb cable issue, but I'm not positive about that.
The new blue color is very pretty. It is more blue than the pix in the JCR looks. There is a plan for a pink one, which I think is going to be a popular color!
If you buy the LS now and the "next generation" comes out in the future, you can trade in your old LS and get FULL PURCHASE PRICE toward the new writer. If you get the LS and decide you don't like it, you have 90 days to return it. You pay a 15% restocking fee.
