Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
120GB? When will Apple learn.
1) 200/250GB version. There are plenty of 4200 and 5400 rpm laptop drives on the market in this size now, wake up and smell the storage.
2) XVid / DIVX Support is a must. If they were smart, they would also look into DIVX Ultra compatibility.
3) Other new formats can be added via firmware/download. Things like WMV9 and some of the other new HD formats would be ideal.
4) Lastly, if they really want to make a truly awesome device, slap a HDMI port on that sucker. Its small and combines your Video and Audio into a single cable. No more crappy custom docking solutions, just a miniUSB port(Control / Synch) and HDMI port (Watch/Listen) and be done with it.
When will *you* learn?
iPods use 1.8" drives. Laptops use 2.5" drives. If you want to carry around a huge-ass iPod, more power to you, but the current limit ( http://en.wikipedia.org/wiki/Hard_Drive#Capacity_and_access_speed ) is 120GB for a 1.8", and the 80GB iPod is pretty much the biggest thing on the market. Just a few weeks ago Hitachi announced their 160GB drives, and do you think that they just MIGHT be coincidentally putting this in a new iPod?
H.264 can kick Xvid's ass any day. And the screen will probably be 480x320, which isn't even enough for the HD stuff you're talking about.
Might want to learn some definitions and basic specs, dude.
