“CNet”:http://reviews.cnet.com/wireless-access-points/apple-airport-express-base/4505-3265_7-32902549.html did a good comparison of the AirPort Express and the Apple Time Capsule. Net, net, the AirPort Express is a good travel router and is lower capacity than the Time Capsule. It is really for smaller networks (10 clients maximum), slower (no gigabit ethernet and no wide channel 802.11n) but it is very small, let’s you network a printer or stream music to a set of speakers remotely from your Mac.
The performance stats are also interesting which show the Time Capsule is about as fast as the fastest router out there and the AirPort is slower and shorter range although 70 meters is amazingly long distance that you’d only get in the open air.
| Router | 5GHz, 15 Feet | 2.4GHz 15 Feet | 2.4 GHz Mixed b/g/n clients | 5Ghz 70M | 2.4 Ghz 70M |
| DLink DGL-4500 Gaming | 116 | 81.9 | 50.9 | 49.7 | 27 |
| Apple Time Capsule | 103 | 65.1 | 51.5 | 42.3 | 21.3 |
| Apple AirPort Express | 66.5 | 52.8 | 50.5 | 18.4 | 11.7 |
