Big brother. One day, if we are not careful, the Internet will be regulated everywhere, and big brother might block it "for our safety". I wouldn't be to worried about it, seeing how SOPA and PIPA failed miserably, I think we can agree everyone loves their Internet without restrictions, and it will stay that way for decades to come.
My grandmas old tower (HP Pavilion from 2005) worked great on XP. Stock, it had 3GHz Pentium 4, 512MB of RAM, and a 160GB 7200rpm HDD. She had it upgraded to 1.5GB of RAM in 2007 and it was used regularly until last year, when she donated it to a local computer shop that provides these computer to schools to have students tear them down and rebuild them. It is to fuel the next gen of geeks.
Also worth noting that this computer was thrown against a wall in 2006 when she got pissed at HP Tech Support after being on the phone for 16 HOURS. She now used a MacBook Pro 2010 model.
Most people are amused by the fact she knows how to use a computer, but at work she actually used an original IBM PC in the 1980's to the late 1990's and was one of the early adopters of America Online (and she still uses her original AOL email!).
Yeah, even the entry level MacBook Air is pretty slow. The only real "UltraBooks" (if you can even call them that) that people should consider are the ones that fit into the same area of the MacBook Pro with Retina Display. I think Dell and HP make some decent competitors to the MBPwR, so does Lenovo. Honestly though, I would pick a Lenovo if Apple ceased to exist. I have never heard of any major problems with Lenovos, especially the ThinkPads.
Hell, it will probably be 15 or more years before I even consider having kids. By then the 128k will be 45!
Only time will tell if the filesystems will remain the same.
This also reminds me I should probably get a 128k before they become more scarce.
