It’s got a user replacable hard disk! This is so fantastic….

Also the little feet don’t fall of anymore.

Yes, it’s bigger and heavier, but the ease of upgrading is making this look a pretty future proof machine. And more affordable: do I need to stick 120GB in there when I could get 80GB now and a brand new 160GB hard drive in a year or two for less than the difference?

With respect to wireless, yes it does make a big difference. I’m not sure I believe the 6 hour claim, but the 2.5 hour DVD is a good benchmark. Wireless will drain your battery fast, always turn it off on trains (unless they’ve got hotspots!)
