If you are talking about speed, then the Company router you were talking about, doesn't it gets shared? & with a Very less Range it's nothing but just a Compromise!
& if someone has TWENTYY Users May be in Joint Family, well then you seriously need some Ptcl 3G or Charr Jee, or may be Individual 4G Cellular! Also then you really need a Router to cover the Whole house & some area around the House!
& for your info the 4G & 3G have just entered & myself used Mobilink 3G it's Veryy Speedy, why Bcuz the Traffic on the Mobile Internet is very less as for now, Only very few people are currently using it'll take time to be common & speed will be affected, evo wingle or Mobile 3G or LTE are nice for personal use or when you are outside making assignments or office work.
For Browsing at home with 6 or more users with a nice Speedy connection Not HEAVY USING & to cover the Range or if you have a small or medium office work, then these routers are still in Use Bro!!! Take some intel!
Basically these routers are Great for Increasing Signal Range & Area! that's their Purpose!
By the way Im Using the Linksys Cisco, Very Smart & Compact, But as 4 users, & normal using these are the Best with Ptcl 4MB/s Connection & im Damn Sure that everyone with a Small family & normal office use with a Speedy connection & nice range these are best.

& these are range Increasing Routers, not Tape Drives, they aren't ANCIENT for sake!
