Here are a few things things / suggestions on these switches...
1) ESW 540 8P - it would be great if you could make the form factor bigger to have an internal power supply.
2) CCA 2.2.1 - Doesn't have all the port roles in for the ESW switches
3) VLAN's are less desirable to setup through the web interface (see point 2)
4) Port numbering... Can we look at setup of the port numbers to be the same as the non ESW switches. For example have the ports not 1,2,3,4 but 1,3,5,7. Consistency is king.
I think these will be a nice step past the linksys heritage.
