No, just a joke on my part. I don't know if Apple think it impresses people to 
know messages were sent from iPads or iPhones, but it seems to be how many are 
set up. I would hope one could disable it, but since I own neither I've never 
tried.

OK. I like the old Sun equipment. Most was built to a very high standard - far 
better than modern PCs.

It basically is, and it's not built to the same high standard as the older SPARC 
hardware, though it is pretty decent. Mine is pretty well specified

  * 3.33 GHz quad core Intel Xeon CPU
  * 12 GB RAM
  * 2 x 2 TB disks (mirrored)
  * 2 x 500 GB disks (mirrored)
  * NVIDIA Quadro FX 3800 graphics accelerator card

I got the machine after some of my Sun hardware was damaged due to lightning. My 
insurers paid for it.

I also have a range of Sun SPARC hardware here
  * Sun Blade 2000
  * 2 x Sun Blade 1000 (one is not complete, so basically useless)
  * 1 x Netra T1.
  * 1 x Sun Ultra 60.

The Sun Blade 2000 has a blown ethernet port on the motherboard, and is an 
insurance writeoff, after I got hit with lightning. Since the insurers left me 
with the machine and did not collect it, I stuck in a Gbit Ethernet card. But I 
don't use it much. I have access to a Sun T5240 if I need it, but that thing is 
really slow, despite it has 16 cores, 128 hardware threads and 32 GB RAM. To get 
any performance out of that machine you need to keep all the threads busy, which 
I gather is possible if it's running as a web server or database, but is useless 
for most scientific applications.
