I was going to post the same basic sentiment earlier. I have a lab full of "future proof" instruments that are now obsolete. Not worthless, but also no longer supported by the manufacturer. The sales and marketing guys will always play up the "future proof" aspect of their toys but the reality is they have no clue whether the company will actually support or extend that product. Past performance of a company isn't all that great a predictor anymore either. I always tell those who ask my advice about technology based instruments (test equipment, computers, etc.) to just buy the very best you can afford right now that meets all your current needs.
