After waiting a full month after ordering, my Sony MicroVaultâ„¢ Tiny 2 GB memory stick today finally arrived. Since I've seen quite some pictures of it during the last month, I did only realize how sma... err, tiny the thing is when I held in in my own hands. Incredible tiny. I tried to illustrate its tininess with a few pics, see later down.
Since my good old Titanium PowerBook has no USB-2 port, I cannot test how fast the stick really transfers files. So, I'm going to make this short.
My stick ships as a 2 GB model. It was formatted as FAT-16, which gave me 1.94 GB available space. I reformatted it to UFS, with which I only got 1.77 GB empty space. I don't know why it's causing such a big loss (more than 150 MB for a partition-table?) and ATM I'm too lazy to find out, so I reformatted it to FAT-32, and there my 1.94 GB are again.
The stick ships preloaded with Virtual Expander™ Software, which compresses uncompressed files while transferring them to/from the stick – but it is Windows only, so I deleted the stuff. I guess I wouldn't need it anyway, 2 GB are way enough, and thank [insert your godness here] I know how to use gzip.
Sony ships a silicone-like enclosing with the unit, which I first thought to be really unusable. It is not too bad, though, if you like to carry your stick with your keychain. I myself am confident that I'll either lose (it sticks quite firmly, though) or break the MicroVault Tiny while my keychain resides in my pocket, so I'll have to find another solution to bring it with me, preferably within my wallet.
And yes, there is a status-light! While transferring data, a tiny (as everything else) green LED blinks at the rear-end of the stick. Since the 2GB model is green anyway, that fits nice.
Did I miss something? Take a look at the pics, I hope they illustrate its tininess, but I guess you need to hold one in your own hands to really believe it. And yeah, I got mine from OHC computer shop, a small swiss online shop, for 89.- CHF. That's about 56.50 EUR or 72.50 USD.

Update 12. October 2006
I've been using it more than a month now and indeed carrying it along all the time within the silicone protection Sony ships with the stick. No problems, looks like the carrying bag gives enough protection.
