The Other Side of the Great (Technological) Divide

This is the consequence of crossing the technological Rubicon that I posted on a while ago. The other day, I found myself discussing and defending the ThinkPads that we're issued at work. I was part of the first group of teachers when the school district made the decision to move from desktops to laptops and was issued a ThinkPad R60. We were told at the time, the "cycle" would be 4 years which is going to be typical and understandable for a money-strapped public entity like a school district vs. a corporation (typically 3 years). Unfortunately the cycle went to 5 years which isn't good, but workable for a machine running XPP. After all, the mission of these machines was to do "office" type applications, email and browser oriented functions. These were dual core machines and could handle those tasks well, however, the powers that be in charge of sourcing and spec'ding these machine are.....shall we say.....lacking in expertise with hardware? Which is where I'm going with this post. It's not a rant regarding them (although their lack of understanding in this area given their jobs is inexcusable), but more so a general issue that's out there among most if not all buyers. I'll just point out that they ordered them with 512Mb of RAM and 40Gb HDD.
We are an "Ebook" school, meaning that the district made the decision some years ago to purchase computers for issue to students and attendant electronic versions of the text, vs. physical books. Given the price, weight and rapidity of change in texts in today's world, it looked to be the right decision. Although ultimately this project is doomed to be abandoned (partially due to circumstances beyond anyone's control), lets just say that the implementation was lacking from the get-go. As most anyone who's worked in a corporate environment knows, the implementation of security software is enough to significantly slow down any computer, so certainly they don't need to be further hampered by being purposely crippled in the ordered specifications! 
Three year ago when I moved to the High School, I was duly impressed by the fact that the issued computer to the students were the ThinkPad X200. And for those who aren't familiar with this model, it's basically a shrunken X300 without an optical drive at half the cost! One day, after listening to the students complaining about the slowness, I decided to look at one. I was horrified to find that it was equipped with 1Gb of RAM! Thinking that this was a mistake or that someone had taken out one of the modules, I checked another.....same thing.....then another......same result. To say that I was a little stunned would be putting it mildly. In fact, I got onto the ThinkPad Forum and had a prolong discussion with other members about why Lenovo would even sell a crippled machine like this, customers' wishes not-withstanding! My contention is that just in our district alone, there are over a thousand people who will have the belief that ThinkPads are horrible computers and would never buy another Lenovo product!

OK; I know that so far, it sounds like a "rant", but it's not really. Although, the "professionals" who's jobs it is to purchase those machines are clearly idiots (yes, I know that a little strong, but they are being paid for their expertise), this is a common issue among most computer users today. Most folks simply don't understand what makes a computer "feel" fast or slow. Yes, corporate (or school district) security is an issue, but you can talk memory with people all day long and the vast majority wouldn't know the difference between RAM and storage to save their life. The fact of the matter is that most any computer made within the last 3-5 years will happily run a modern OS (eg. Windows 7) and it's basic apps if given the correct amount of RAM. My "rule of thumb" is to double whatever Microsoft lists as recommended.....then double that every time they come out with a major service pack. 
 
A good example was what happened with Windows XP. It was originally designed to run on 256Mb of RAM. By the time that Service Pack 3 came out, it needed to have 2Gb to run well. So it basically went like this: 
  1. Windows XP- 256Mb of RAM
  2. Windows XP SP1- 512Mb of RAM
  3. Windows XP SP2- 1Gb of RAM
  4. Windows XP SP3- 2Gb of RAM
 
With Windows 7, I've set a 2Gb floor and have really only run 4Gb or better on our own machines. However, within the last year, another dynamic has come on the scene. The all-conquering solid state drive (SSD for short). This along with a adequate amount of RAM has become the main ingredient in making a machine feel fast. Boots happen within 15-20 seconds, programs launch instantly and files are accessed almost immediately.
  
The correct combination of these devices can make the sweet-spot of the 3 year-old notebook computer a perfect storm of functionality. Take any corporate level computer of this vintage, ranging from the Dell Latitude E6400 that I've been buying up for clients to the X61 that's destined to be my daughter's replacement for the aging X30 (yes, that's right.....a PIII-M machine). Combine these computers with 2 to 4Gb of RAM, an SSD (stirred, not shaken), add Windows 7 and anyone can have themselves a very nicely functioning notebook for around $250, or less.
Which gets me down to my last point. Our school district finally got it's wits about itself and started buying machines with adequate RAM. The L420 that was issued at the end of last year has 4Gb of  RAM on board. However, this machine is far outperformed based on "feel" day-to-day by my 3 year old X300 and the 4 year old X61 equipped with the same amount of RAM and a SSD!
