Hello Sean!

How's the 500GB SSD replacement going?

I've just ordered a refurbished T540p (W7pro, and lower-cost i5 generation
processor) with a 1TB SDD.  I tend to need a numeric keypad a lot so the one
built in will be quite nice.

My T60 Thinkpad (XP) was creeping out of space on C: with only 2.5GB free. :(  
I deleted old files in $NTinstall and $PatchCache$ and gained about 3GB.

Then, the idea is to transfer the programs from the T60 to the T540p with
Laplink.

Then, the next step might be to replace the modest 230gb HDD in the T60 with at
least a 500gb SSD, (hoping that the SSD will help extend the battery usage that
I sometimes need) and then replace the XP on it with Linux Mint which performed
beautifully in live-cd mode.
