To the original question, everything is made like it's Disposable now.
I also got a scope from the 465 family (475) as a first-scope. It still runs today, but I gave it to a friend back in 2005. That same year, I bought my first Digital Scope, a TDS5032B.
Three-quarters of the way through the warranty period, it crapped the bed. Tek was proper and did a warranty job on it (HDD failed). Since then, it's had reliability issues - something on the windows operating system craps the bed too. You have to flatten and reinstall. A few months ago, I decided to buy the jitter analysis software - a simple dumb unlock key.
Tek stopped supporting the scope about four years ago. Including software keys. Go to Tek.com, and try to find anything on the TDS5000 series, and you're better off playing a Rogue-like on Tourist mode (near impossible). This also means that 'free money' to them is not something of interest. A month later, the scope just outright failed and is bricked. It was something I worried would happen.
When I bought it from the proceeds of my first major contract, it was $7,300 new. The same thing "today" from Tek is $15k. It's till PC based too, which means the whole of your instrument is held in the balance upon consumer products (the computer) lasting. In other words, modern gear today is built as a commodity, while commanding instrumentation grade dollars, and must be expected to die in 3-5 years.
My TDS5000 scope will be replaced with a Rigol shortly, because if it's a choice between a $15,000 something that will die in 3 years, and a $5,000 something that will die in 3 years, I am better off not spending the extra $10k for the luxury of having "Tektronix" printed on the front.
