Differences(Casing e.t.c) between SZ 650NC and SZ 691NX

So, i know that 691NX has more powerfull processor, hdd of bigger capacity, several questions and comments:

1)i see that 691NX has Preimium Carbon Fiber Casing and 650NC has just Carbon Fiber & Alloy Encasings.
could someone post pics, photos of 691NX to see the diffrence. And in fact which casing is better, is it worth to to pay for 691NX casing?

2)Could be antenna of Built-in Sprint® Mobile Broadband high-speed EVDO WAN in 691NX removed? and would it be working in the world(exactly Russia) or is it only for US?

Thanks Sponsi.

 

Could someone post photos of SZ691 N/X with opened lid.., to see the touchpad area, it seems that N/X has another fringe of touchpad and buttons.

 

The antenna can be removed, however you would need to buy a little cap to cover the hole. I think the WWAN is also available in Russia, I know the last series of SZ's had Cingular instead of Sprint and that was US only but the new 600 series WWAN I think will work in Europe as well.

I'm almost 100 percent sure the 650 and 691 have the same interior. If you want the fancier lid, get the 691NX, but keep in mind it's hard drive runs at 4200rpm as compared to the 650 5400rpm.

man the lid is so nice, but where can you get the little cap to cover the hole?

 

Yup, I love it too. I've seen other threads asking the same, I recall someone ordering one from Sony. I would also suggest looking on eBay.

I'll try to find the thread(s) this was previously discussed in.
