You may want to check out SUNs ceo's comments on the netapp issues... This dates all the way back to 2007. From the comments above this appeared to be something new. http://blogs.sun.com/jonathan/entry/harvesting_from_a_troll
have you looked at the cost of a new sun machine? Very inexpensive. Anyway, if sparc were an option I would get a blade2000 off of ebay. my blade1000 is 11 years old and has never had an issue.
A used ibm x30 is 200 dollars with a 60gb hd 512ram and 1.2 ghz chip. 3lbs and an 1inch thick. In another year it will be 100 dollars. Why bother with a new computer if all you want to do with it is travel, net, and type?
