One month ago I published a review of Google Maps for Mobile and Windows Live Search for Mobile which you can read here. Today Gear Digest have published their own, much more detailed, comparison of the two as well as Yahoo's similar offering. Unlike myself who just did a feature-by-feature comparison Gear Digest make a firm recommendation (if you can be bothered to read that far - its 8 pages in). If you think about whose blog you are reading right now and the fact that I'm pointing it out then you can probably guess what they recommended.
Read Gear Digest's review here.
Thanks for the tip.
