So...impressions after not quite a week...
Prime is very cool. However, I am experiencing wifi issues. They are not to the point where, depending on your use of the tablet, they make it unusable. But they make you have to think a little about placement of your routers, configuration, etc., more than you might want to. Comparisons also come up lacking.
IE, I just tested with a colleague in the office how browsers speeds were in different locations. He has an iPad2. When we were in areas where there were open line of sight to the antenna, the Prime and iPad 2 were on par with each other. However, when we moved to areas around a corner, while he could still browse relatively quickly, I could not even browse (in Dolphin or Chrome). As soon as I walked around the corner, sites came up quickly.
Interestingly in my house I was able to connect/browse/and stream video to some level upstairs (router & AP is downstairs). So not sure if something else is at play...
However, it does not look to have the same reception as the iPad2 at least.
I plan on keeping it, aside from this, I love it...but I might contact Asus to see what can be done.
UPDATE:
So, I rebooted it, guess I could have just cycled the wifi (though I have done that a few times today just testing things), and my wifi was up to 3 bars. After walking to the exact same spot it all worked no problem.
I think one of the things going on is that it doesn't automatically switch APs based on whichever is the strongest. And perhaps I was connected for some reason to one that didn't reach that location.
