iphone? or droid? eligible for upgrade and can't decide htc atrix
Tech challenged? Unless you are interested in becoming less so, I'll actually recommend the Iphone. You can tinker more with a Droid, but the Iphone is geared towards those not particularly interested in doing so, and has a larger selection of apps which have the benefit of working with/on a defined, limited set of tech+operating system, so they generally work smoothly. Droids come in a much wider variety of hardware units, and there are several OS versions in service. As a result, apps might or might not work well on the phone you end up with.
Flip side - I've been a Droid fan since the first one came out a couple of years ago, and have always thought that the Android Market has plenty of apps available (does it really matter that Apple's app store has half a million apps, and the Android Market has "only" a quarter million or something like that? *I* don't think so). Currently using a Droid Bionic, one of the newer Droids with a dual-core processor and access to the 4G/LTE wireless network, and I'm pretty satisfied with it. I've had very little trouble with app incompatibility - and only with stuff I had no real need for. Biggest problems, lately, are that there are still issues with switching between 3G and 4G networks that can result in temporary loss of data connection (may be solely a Verizon issue - I don't know if AT&T is having similar troubles or not), and manufacturers/phone providers are catching onto the notion of loading bloatware on their phones. There are a few programs which come on the phone which I will never use (because other options are cheaper and better), but in stock form I can't uninstall them and if they're ever used, it's something like $10/month. There's an option for that, too - by rooting, it's possible to gain unlimited access and uninstall even those "untouchable" programs, as well as getting into loading custom operating system ROMs.
Most important reasons to go Droid, for me, are that with a Droid you can (generally) change out a battery and you have removable storage (microSD card), neither of which is an option with an Iphone.
