too many bad detail on the new bsg, wire comunication is a bit hold, paper is also old, glass when we have laser correction, the clothing are so 20th century, there at least 7,000 more advance that us, the look a bit past due on a lot of stuff compare to us.
Last I heard they went against networked pc's because it was turned against them as Capt_Bearslayer_XC said. Also, I've yet to see a ST type PADD or notebook, thinkpad or any other device that feels or acts as good as a piece of paper and I'm no Luddite, I've tried! lol.
Glasses, well that could be a character device to give the impression of thoughtfulness that you'd expect from Adama.
Clothing fashion generally repeats every decade on Earth according to social conditions so why not in BSG? I don't think it's particularly meant to represent a future evolution of ourselves, more like a parallel with advances in certain areas beyond what we have and maybe a bit behind in what we have too. Genre comparison, don't forget, Han Solo in a galaxy far far away a long time ago wore a waistcoat that many here would call old fashioned. Yet he had a blaster and a fast(ish) ship.... and a stinking wookie best pal.
Um, you know...the original BSG was soooooo 1970's that it's not funny. Look at their hairstyles! Look at their clothing!
The creators of the new BSG have stated several times why they went with the retro-tech on purpose, and several episodes have expanded on that. First of all, the Cylon attack was made easier by the fact that newer battlestars and other ships HAD networked and wireless computers. These wireless systems and interconnected systems were crashed by a viru when Bill Gates, um I mean Gaius Baltar gave them access to the network systems. They had over a year to study the colonial codes and design a virus to take them out (or several viruses).
The Galactica was built during the original cylon war and thus designed to be RESISTANT to computer viruses. All computers were stand-alone with no networking. Communications were all backed up with SOUND-POWERED phone systems. There were no automated landing systems or anything else the Cylons could use to implant a virus. Further, Adama kept the Galactica in that condition. As commanding officer he had standing orders against networking systems, etc. and he enforced them.
Now if you look at the Pegasus, which was a newer design of ship, you'll see more of your 'advanced tech'.
Nope, they don't have 'lasers' or other inefficient weapon systems. Let's face it, the amount of power it takes to use a laser against a hardened target is not worth the energy/cost ratio. Instead it's easier to put a projectile out there that blows away the target for a lot less energy.
Also, 7,000 years is not accurate as far as time relation...it's been two thousand years since the Colonials left Kobol and founded the Twelve Colonies. Yep, a measly two millenia.
Now did the 13th tribe (earth) leave before or after them? That's not yet been discussed.
