Anything more than the 2.2lbs of my 5-year old X1 is "heavy"

especially when it has poorer connectivity and a huge price tag.
The Apple hardware looks good, but in the end it's just a netbook, and one that needs external dongles to connect to everyday things like LANs and external screens. Stuff like the non-replaceable (non-existent) "hard drive", non-standard BIOS, and difficult-to-replace battery, means that it misses out on the basics while sitting there and looking extremely pretty with a very high price tag.
Great if I wanted to run OS/X or needed high performance in a netbook, since other machines don't do that part very well. And great were I wealthy enough not to care about the price tag.
But for less than a third of the landed price, I've got a machine with better connectivity, a replaceable battery, replaceable drive (with difficulty), and similar form factor and weight. No dongles, either.
I'm happy. Wealthier (real or imagined) folks will undoubtedly go for the jewel-encrusted vib^H^H^Hairbook and be even happier!

Cheers
