Well, I recently bought Tam Dao, and the lovely SA gave me a sample of a truckload of other Diptyque frag! 
So, here are my thoughts on these frags... Please note, I live in hot and humid Singapore, so these scents will probably smell totally different in more temperate climates.
Virglio:
At first, it's a herb-laced blast with a dash of mint... after a couple minutes, it smells distinctly of Licorice. On the drydown, however, it resembles the edgy, incense side of Kouros with a dash of Cedar and Basil. Interesting.
Eau de Lierre:
They didn't sell this in the shop yet, but had samples. Quite an interesting scent... At first, it seems to have a strong dash of citrus, but this quickly mellows to an earthy, rich scent that reminds me of incense with capsicum and Ivy. Dunno if I'd put it on my must-buy list, but it's interesting. Then it settled more... And it's a wonderful, fresh ivy, a little musk and woods. Wow. It's actually awesome, but on drydown smells almost mainstream oriental, and it stays close to the body, and thus may have problems standing out from other slightly similar frags such as Platimum Egoiste.
Tam Dao:
Wow, easily the best sandalwood scent I've ever smelled. Awesome. To my nose, some rosewood, some Ambergis, all tempered by smooth sandalwood. Not too good for the hot outdoors, but wonderful in the office.
Eau d'Elide:
At first, the sweetness almost made me gag. It's like inhaling concentrated vanilla ice cream mixed with Bazooka bubble gum. On the drydown, it's more like powdery orange sorbet. Awful. But an interesting room freshener.
L'Ombre dans L'Eau:
Ok, so it's supposed to smell like a wet garden... I'd have to *slightly* disagree... It smells like a wonderful wild rose after the rain, with a dash of currant? Dunno. Don't care. It's lovely.
Philosykos:
First blast: The scent of fresh-cut grass and you're lying in the field. Unbelievably green. Settles to more of a fig/cedar mix, but never loses that "fresh cut grass" smell. Awesome, I almost regret picking Tam Dao over this.
Eau Lente:
Again... Wow. At first, it smells like a fresh blast of pine, with cinnamon and clove. Then settles to a wonderful rich, burnt-vanilla smell thanks to the Opopanax. Wear in moderation... This juice evolves a LOT, and really reaches it's peak after 3-4 hours. Awesome.
Olene:
Very light flowers... Very feminine. Not for me, but my female officemate loved the sample for herself.
Ofrésia:
Very wonderful, gentle Fresia flowers on a woody/peppery base. Fairly linear, though it takes a good hour for the peppery notes to come out. It's nice, but not quite my thing.
Opôné:
A very rich, spicy rose scent with a great blend of saffron and spices. Quite nice, really, but poor compared to L'Ombre.
Do Son:
This scent confused me... It's got such a massive, unbelievable evolution, but always smells like asian spices and asian flowers. There's a definite bit of honey, some rose, some cucumber? Then it settles to what seems like Iris and musk. Great stuff, it smells different every time i smell it.
Jardin Clos:
Ghah! Very feminine. Hmmm... Rose? Lilac? Some other flower, a dash of woods... maybe cedar? Very, very feminine, reminds me of a perfume my mom would wear. Made a great gift to the same female officemate.
