TI likes to point out that they waited out the pre-802.11g frenzy so that they could get their 11g chipset right the first time. Time will tell whether that was the correct strategy for maximizing market share, but it looks like USR has gotten a pretty solid - but not perfect - product as a result.
With a large feature set, upgradeable antennas, superior range vs. throughput performance and flexible management options, there's a lot to like in the 5450. I'd just like to see USR get the WPA upgrade out, provide a real user manual, and cool it on the 100Mbps hype. A good 802.11g product it is, but 100Mbps it's not!
Just as I was posting this review, I checked prices and saw that the 5450 had leaped from a low of about $100 a few weeks ago to around $200! I hope this is just some sort of glitch in pricing, since it's about 60% higher than the street price of other 11g access points, and will clearly put USR at a competitive disadvantage.
