Feature-wise, the main things the RV082 and RV016 add over the RV042 are a bit higher performance, more WAN port flexibility and more IPsec tunnels (100 vs. 50). Table 2 summarizes the WAN, LAN and DMZ port situtation.
|RV042||2||4||1||Second WAN port shared w/ DMZ|
|RV082||2||8||1||Second WAN port shared w/ DMZ|
|RV016||7||13||1||5 LAN ports can be configured as WAN|

The RV016 also gives you five more PPTP tunnels than the RV042 and 082—a total of ten.
Doug did a good job of walking through many of the new GUI's features in the RV042 v3 review. Note that the new v4.0.3.03-tm firmware fixes the GUI access problems Doug had with Firefox.

Here's a summary of the RV0XX series' other features, with differences between models noted.

Despite all the features, the RV0XXes don't do everything you might want from a small business router. For example, VLAN handling isn't as flexible as you can get in most "smart" switches.
Figure 5 shows the Port Setup page that contains physical port disables, priority and speed / mode settings. There is also a VLAN selector, which looks encouraging.
Figure 5: Port setup
You can't assign LAN ports to multiple VLANs, nor can you assign WAN or DMZ ports to any VLANs. And 802.1q VLAN tagging also isn't supported. But Cisco tells me that assigning ports to different VLANs will block broadcast traffic and keep them from accessing one another, while still supporting Internet access for all clients.
So the most common use of VLANs, segmenting a LAN, but maintaining Internet access is handled without needing to mess with PVIDs and other complications you run into with managed / smart switches.
The RV0XXes also don't support multiple subnets, which more advanced networks might need.
All the RV0XXes do support multiple subnets (option under Network - Setup).
