Yes, support is another important issue. Apple and Thinkpad support are top of the line. Apple users swear by their Genius Bar and I swear by dozen of times I used Thinkpad support.
I use (let call it abuse) my Thinkpad heavily the past 4+ years. Thinkpad used to come with 3 years warranty (not sure what the deal these days). I have my laptop serviced numerous times for worn out parts (LCD, motherboard, fans, etc) so it's definitely quite a ride.
And when you get used to this level of service, there is no way you will go back to Dell customer service.
By the way, I have my own Thinkpad certified dealer who provide me with stock parts when my warranty expired.
Here is the list of a few modules he quoted me recently. The guy runs a business out of Long Island, NY
Here are the specs and prices of a few ThinkPads that I have available.
The X series are considered ultraportables. The T series are the successors to your T60.
