The A-DATA 16GB 350x Compact Flash card is a good step up from the previous 266x version. The write speeds have improved noticably from ~20 MB/s to almost 30 MB/s. The read speeds of around 50 MB/s are fantastic and should make it a great choice if you require the best possible read performance. The falling prices of SSD drives do limit the use of the card as a boot drive, but if you're going for for an extremely small form factor PC and are willing to overlook the GB/$ ratio for this additional performance, then the A-DATA 350x 16 GB Turbo card should be the perfect choice - especially if a 2.5" SSD won't fit into the space available.
