I wrote a long review and the net died before I could post it
(non router related, someone picked up the phone)
So here's the quick and short version of it. Everything installed easily enough. Macbook speeds 6MB/sec download standing right next to the router.
2-2.5MB/sec download, 3-3.5MB/sec in the bedroom.
PC 7.5MB/sec max in the bedroom. Syncing with the USB client at 270mbps
Overall I would recommend this product. It definitely is an improvement on g, mainly on throughput speeds, less so on range. If you're in the market for a wireless N router. You could do way way worse than get the N+ router and usb key.
I'll report back as the days go by and see what other hidden issues or reliability problems come up. But so far so good.
Thanks to Tim Higgins for doing the review, and brining it to my attention
edit- I placed the USB key on a stool outside my bedroom, so it would be 4-5 meters away from the router. Vista registered 11-12MB/sec doing an SMB file transfer. Not bad eh, pity I can't just leave it there as it gets in the way of people walking by.
Macbook is syncing at 130mbps and can get upto 6.8MB/sec when I'm standing next to the router.
Overall N is quite impressive as long as are fairly close to the router you should be ok. If range is your priority, definitely stick with G.
