You have no idea what you are talking about.
Technet has not been about the help pages for years - Technet was about providing legal software with keys for evaluation for as long as you kept your Technet sub going.
As other posters have said, 90-180 days is not enough to learn/evaluate platforms. I for one would not have learnt anything useful for Exchange 2010 if I had it running in sandbox lab with no real email flowing through it - I use it as my home email server, for 5 accounts. I migrated my previous Exchange 2003 installation into it, an arduous task that took weeks to complete correctly and I learnt SO much in the process - that's not something a dry lab environment could have provided. (and for those that say I'm falling foul of the T&Cs, I'm not - I don't class my home environment as a 'Production system'.)
Losing Technet for me is a big loss - my alternatives are MSDN (too expensive for non-contractor who likes to dabble/upskill), or the MS Partner programme (also fairly expensive and maybe not available to individuals). I might just say f*ck it, and migrate over to non MS software over the next few years, turning my back on 20+ years as an MS whore.
I think MS have lost the plot recently, and seem to be doing their best to alienate all their current userbase and developerbase.
