Pros:

Beautiful screen

Easy to use

Big screen

Lots of POI (I like the AAA info that comes with it)

Cons:

Comes with 2007 maps. Even though I purchased it in Aug 2008, Magellan still wanted another $80 to update to 2008/2009 maps.

Does not offer street name announcements (important for me when using it on my motorcycle).

Short battery life of about 3 hours (again, important for motorcycle)

Conclusion:

I returned it to Amazon and got the Magellan 3250 in its place (same product with smaller screen but includes street name announcements)

The magellan 4210 has a number of good features such as: light weight, battery backup, large screen and ease of mounting.

This GPS is excellent and one of the best purchases I've made. The screen and voice clarity is terrific and the ease of operation is outstanding. Open the box, tap, plug in the address and go. Delivery was fast and in excellent condition.

The Magellan Maestro 4210 is a portable, user-friendly gadget, with a good size screen and lightning fast in picking up satellite feeds. I strongly suggest to GPS buyers to consider Magellan over their competitors as it is the pioneer of GPS and has perfected the technology everytime they come up with a new model. So if you're just in the market of a full-time GPS less other whistles (i.e. MP3, bluetooth), this is a highly recommended model that is fool-proof from getting lost. I am very satisfied with Magellan products and this is so far better than my first Magellan (Roadmate 760 - still using it) that I had purchased 5 years ago.

Phew, I'm so glad I didn't listen to the negative customer reviews for the 4210. If you read the item description correctly, you'll see that this system does not have the text to speech capability (the 4250 and other higher end models do), but I'm not willing to pay an extra $70+ to hear the name of the street read aloud. This system has what I wanted: widescreen, thin (0.7"), a lot of Points of Interest (6 million should do), and helpful screen guides (I really like the ETA function). I'm glad I waited for the prices of GPS systems to go down a bit, and I'm very happy with what I got for my money.

This is my Tomtom review:

I brought this as an upgrade to my Magellan 2200t, and even through it had more features than my 2200t the directions were terrible. I know that any GPS device is not 100 percent on the money and in a lot of cases it is off a little. The Tomtom was often trying to make me take turns onto roads that I didn't have to take to get to my destination. One time I followed the directions to see where it would take me. I made a right and then just a little while later it told me to make a left. That left would have put me in a ditch and into the woods. And the deal breaker was the way I had to access the Point of Interests (POI). I now have a Magellan 4210 and while driving if I see a POI on the screen all that I have to do is tap the screen to view a list of all the POI in the area. Now with the Tomtom I would have to work my way to the menu screen to see something or find something of interest. Also in bright sun light forget about looking at the screen. And my Magellan screen changes from a daytime screen to a nighttime screen. But I will give them credit for a few things, free map updates, and you can customize the voices. I'm very happy with my Magellan 4210 and even happier Amazon allowed me to return the item.

Short but sweet Magellan 4210 review:

Brought a Tomtom to replace an old Magellan 2200t big mistake because the Tomtom sucked in my opinion. This 4210 works great and is as accurate as any other, I'm grateful that I was able to return that piece of crap Tomtom. I would highly recommend this GPS to anyone looking for a great toy for the car. Get a Magellan it will not disappoint.

I had a Magellan Roadmate 800, which I really liked. Magellan's Map Upgrade wiped the hard drive clean. After spending several days on the phone with their Indian Tech Support, a supervisor gave me an RA number to ship it to Houston, where they would reinstall the original maps and the upgrade. Needless to say, that went badly as Magellan's Non-existant Customer/Technical support lost the unit. They finally agreed to ship me the new Maestro 4210. The 4210 does connect to the satellites quicker than the 800 but is not as accurate. My home address is about 3 miles away from where the 4210 says it is... The position hops back and forth between the road I'm driving and any parallel roads nearby - and it always tries to reroute me when it thinks I'm on a different road. Problems I did not have with the 800. Only ATMs POI's show up on the map as I am driving. And only the female voice is available. The maps on the 4210 still show streets that have been gone for 7 or 8 years - and I know that Tom Tom's maps are accurate in this regard. I wish I had bought a Garmin or a Tom Tom.
