I can afford to get a new large memory card in december so i'm going to get a 16GB CF. I went to a website that i've been watching for a while now and was amazed at how far the price had dropped, but the biggest surprise was that they had fairly cheap 16GB SD-HC cards too. With the third party drivers to run SD-HC on my X51v I could get both and have 32GB! I'm very tempted.
I'm definately going to get at least one and I reckon it will be a CF for the reasons that 1, its cheaper, and 2, I worry that they might stop making them soon now SD cards are becoming so big.
Anyway I will have to wait until december but I figured I would give a heads-up to anyone in the UK thats looking for a high capacity card.
PEAK 16GB Compact Flash Card £68.78
PEAK 16GB SD-HC Card £87.38
I should point out to anyone that doesn't know that the SD-HC card will only work in a Dell Axim X51v with 3rd party drivers. If you don't have one of these pda's or if you do but you are not willing to flash your device then don't get this card because it won't work.
