In laymans terms perhaps you could argue this. But in laymans you can also argue that you get every single edition, every single book ever made of D&D for free via pdf.
As a roleplayer though. I think D&D insider is a great investment (for $9 a month), it covers Dragon and Dungeon magazine, it has pre-made adventures, it has a character generator, a full monster and treasure compendium, it has world-wide access to 5ed playtest, it has a free lively forum. Plus plenty of articles to get you ingrossed into Forgotten Realms.
The creation of essentials, was mainly for the use in D&D Encounters, where we signed up with our local comic shop and Wizards of the Coast sent us two free copies of 'Beyond the crystal cave' inclduing free double sided maps, tokens, pre-generated character on high quality card stock, and a full advenutre. Plus two free copies Lair Assault 'Talon of Umberlee'
Beyond the crystal cave sells on ebay for £130
The previous Lair Assault called 'Forge of the Dawn Titan' sells on ebay for £60
The Essentials handbook is only needed for playing Encounters, and for the 6 weeks I have been playing. I have not used my rules compendium once, it costs me £10.
One of the most expensive items I have purchased so far is my miniature which was from Reaper.
The far most expensive cost is for the DM, when he or she wants to purchase minis, extra tiles, or maps. And I got to say it can get expensive at this point. But then so is amounting a 1000pt Space Marine Chapter for Warhammer 40k. If it wasnt for my DM then I doubt I would have played so much D&D in the last year. But he wanted to collect, he had the money to purchase products, and without me playing then he would have had one less character to try and kill. In the year we met and played. My DM went from.

And dont get me wrong I loved 2nd Edition, Larry Elmores work was amazing, some of the rules were awesome, the activity of running long campaigns purely created from a guys head and his love for graph paper was fascinating. That doesnt mean any of that isnt possible in 4ed. It purely is, about roleplaying, if your DM allows you to explore story after story, with decisions being made with the outcome of a die roll, then I love it!
I would love to hear players reasons why 3.5 edition was so much more awesome than 4ed. Because when I purchased my copy of the 3.5 players handbook, leather bound et al. I just starred blankly at the awful art, and rules that just looked simular to 2nd edition, and wondered how the hell I would find anyone in their right mind who would sit down and play with me. 4ed is accessible! Anyone can play! And its simple to join in on a game if a local store plays Encounters.
