I had a sony T1, and I thought it was great - perhaps slightly expensive, but still solid - still working. Sure it had it's flaws, but for most people it's fine.
It really depends on what you want out of your camera - how much stuff like customisability, image quality, user friendliness, range of shots you want etc matter to you. For the most part though, all portable digital ceameras are all pretty decent at doing what they do, which is largely to take snapshots.
