I was bitten with the bug to purchase a new Sony Vaio TT Series, but a combination of high price and having to part with my beloved TR3A kept me from doing so.
After several years of faithful service from my TR3A, I decided to finally do some upgrades. I added another 512MB of memory for 1GB total. I saw a bit of an improvement, but it was the addition of a Kingspec 64GB PATA SSD ($240, ebay, shipped from USA) that made the big difference. WOW! This machine now fully boots in just over a minute. Internet Explorer 8 comes up super fast. MS Word 2007 comes up about 3 or 4 times faster than before. It comes out of standby instantly, and the machine is very quiet. It is weird seeing the hard drive activity light yet hearing nothing but the faint whisper of the CPU fan.
I highly recommend the Kingspec SSD. I did a complete recovery using the excellent Symantec Backup Exec System Recovery Desktop 8.0 (Found for $17.00 on Ebay) in about 37 minutes.
I will not miss my S-l-o-o-o-o-w, noisy 40GB Hitachi HDD.
UPDATED: 7/3/09. Everything I said above was running XP SP3. Windows 7 runs super fast on this same machine.
