Thanks Lizzie, this is very valuable info. I am still using the Dex 7, and not so frequently because of too many big inaccuracies, and false alarms. Medicare does not cover CGM's so I will have to stick with the Dex 7. I do want to switch to the G4 eventually, and posts like yours will be very helpful.
Good luck with future sensors!!
I'm very interested in how you got the program working on the Mac. I'm a computer illiterate, so can you tell me step by step what you did? Private message would be OK, too! Thanks!
Well, step by step, I asked my boyfriend "Can I install this dumb Windows only program on the Windows side of your mac?" Then I started the computer in Windows and downloaded and installed the program.
Since that's not very helpful, here's a bit more detail, though I'm not an expert at all. If your Mac is running Leopard or later, it comes with a program called Bootcamp. Follow the instructions found here - http://support.apple.com/kb/HT1461- to install a purchased (or stolen, whatever you want, you just need the disks) copy of Windows onto your mac. Following installation, you now have the choice of whether to start your computer with the Mac OS or Windows. You just need to hold down the option key right after you press the power button at start up. A gray screen with an icon for Windows and an icon for OSX will appear. Pick Windows, then open Internet Explorer and go to Dexcom.com to download Studio (It's under the Products menu). Download, install, say yes or ok to every window that pops up. To switch back to the mac OS, you have to restart and hold down option again. That should do it. First thing you have to do is buy, beg, or steal a copy of Windows.
Hope that's helpful.

I'm playing my G4 pretty much by the book in terms of calibrations, and I am finding it to be more accurate than my 7+. I wore one for two weeks and it never wavers -- not at the beginning; not at the end. Fine all the way along.
My exercise tends to make my sugars go wacky. Today I rode 13.2 miles on dirt, climbing 2,470 feet along the way, burning 1,396 calories in 1 hour and 45 minutes. I hit rock bottom at the top of the climb, and knew I would pay the (low) price, but offset it with Sport Beans and a bit later with some Shot Blocks. Alls well in the end though -- the G4 is tracking everything fine, even my post ride highs. :)
I'm loving the G4 as well, for many reasons but mostly the hugely improved accuracy. When the seven + yelled at me during the night, my first thought was always..another false low, and I was often right. I'm dealing with the consequences of steroid injections/BG right now so it's been challenging keeping my BG in line. The G4 woke me yesterday morning and read 43; my meter said 45. I won't ignore it or be tempted to throw it!
Meal spikes/hills are much more accurate as well. It doesn't seem to have the 10 minute lag time to catch up with fingerstick readings. Doesn't make sense but I'll take it! I'm calibrating when it more than 15% off. The calibration alarm now is 12 hours from the last calibration, not 12 hours from the last time it ASKED for a calibration.
I've found it equally accurate in the 150-160 range (as high as I've gone) as well as the middle ranges. The battery seems to last longer, and there's a nifty little cover that slides over the micro usb port when not in use. I got to day 10 before I pulled it out in my sleep.
I did stick a label on the back that says Medical Device, with my first name and phone number. It looks so much like an iPod....
I agree with everything Lizzie said about appearance/usability. The scrolling is improved as well, and I do like the pink ;)
I'm just four days into my G4, and my comments would echo yours, except my "accuracy" has been excellent since the first reading. I started the G4 after work last week...and entered the first calibrations at about 10 pm. Something I would have never done with the 7 Plus because I found it was always a poor performer the first day. But the G4 was good that first night and has continued.
I wear the sensor on my abdomen, and the thickness of the new transmitter initially felt odd, but I have gotten used to it.
I'm glad I was able to upgrade. After almost 4 years with the Seven and Seven Plus I was ready for a change.
Lizzie - Thanks for the comprehensive review. I'm on day 12 of my first sensor. The accuracy seems very good but I have not kept track of the overall fingerstick/G4 correlation. After reading another thread here regarding calibrations, I cut way back on the number of calibrations and let the receiver tell me when it wanted one. The accuracy seems to be better now. The biggest thing that sticks out is the absolute lack of data-dropouts. Other than my startup day and the day 7 two-hour blackout/restart, my system has not missed one data point. Very impressive.
I added a separate post this morning to inquire about others experience with the increased range and impressive lack of data dropouts. Your experience on this aspect agrees with mine.
