Does it have enough memory for running multiple apps? That's always been S60 devices biggest flaw (well and it seems less stable than WM5 - but only marginally so). Personally I'd like Nokia to abandon S60 and switch to WM5 - you could get some great devices - can't see it happening though.
I have only owned my Nokia E61 for a few weeks now, but I must say that I am very pleased with it.
As I mainly SMS on my mobiles, the qwerty keyboard layout suited me right down to the ground. It only took a few texts to become familiar with the function keys, and I was composing and replying at much faster speeds than previously accomplished.
The 64MB MiniSD card was immediately replaced with a 512MB card, and mainly holds my custom ringtones and wallpaper graphics. I was delighted that these files did not have to be copied onto the main phone index, thus leaving that memory free for other apps. Individual contact ringtones (mine are all truncated mp3 based files) are linked from the contact details to the MiniSD card. This is a feature very sadly lacking from other manufacturers, which insist that you copy the tones into phone memory, wasting that memory and limiting the number of tones available. The same with your custom graphics. No waste of internal memory. Well done Nokia!!!
A major drawback for me, as I am a major texter (mainly SMS, not so much MMS), was the absence of the contact ringtone identifying the sender of the SMS. There wasn't even a murmur about it in the blurb, but my old trusty Motorola E398 was able to do this. I always knew which one of my cracked friends was replying to my SMSs because their contact ringtone would sound off (only playing through once, as opposed to 'repeating until you answered it' with normal voice usage) - and as you can well imagine, because I have had this feature in the past, with such a prestigous unit as the E61, I'd like to see it as a standard feature. Of course, you can assign any built-in tone or custom tone to any of the messaging systems on the E61, but it will only play the listed tone for each type of message, whether it be e-mail, MMS or SMS. I hope Nokia makes this particular feature a standard, or at least brings out an app to do so.
The absence of a camera, personally, did not affect me in anyway. The novelty of the feature wore off with me a long, long time ago. I was also less than impressed with the various claims spouted by the R&D teams. A 2MP camera on a mobile phone does not equate to a dedicated photographic imager. Sorry. It could be seen as a handy feature, but the more I viewed images, the more critical I became of the feature. All of my background and wallpaper screens are from dedicated units, and as such, the image quality is quite obviously higher than that of most (not all) mobile phones and PDAs. I still have images captured from my list of previous phones, but they look like they came from mobile phones. There is no mistake.
The utilities available on the Nokia E61 are all good, I have found. Obviously, not a replacement, but an asset to your computer's tried and tested applications. The ability to view and partially edit features of docs and presentations is handy. One of my first objectives was to implement Adobe Reader from the Adobe site (I downloaded the incorrect one first, and the E61 wouldn't run it, but I did get the correct one in the end) and it gave me limited access the pdf files. I say limited because the phone is obviously not going to load up an eBook or anymore than a few pages. But, to it's credit, it can load a few single page pricelists that I carry around with me. These are indispensible to me, and I thank Adobe Systems for allowing Nokia access to such a handy utility! Don't expect a Mobile Office! It won't live up to that expectation. But, as an access to view some of your documents, it's great. Check that it's what you need first!!!
My last paragraph falls into the category of "Listen All Manufacturers": I am, as well as many mobile cellular network users, quite proficient in computer use. Without compromising the sacredity of your product, you could allow the person who buys your product greater flexibility in moving about it's systems. I remember back when the IBM PC was so rigid, that everybody used the same applications because that's all they could really get. Now we have USB and Bluetooth and Wireless access. But we're really only following those items to the paths and doorways that you have left open. I realise in most cases that this is a good thing - you don't want just anybody fluttering around inside your product. I have long since pondered over a limited pathway system. Where Customisation of your mobile phone was truly advantageous to the end-user, but kept the product as part of the original manufacturers specs. Bear with me this example...
When ON is pressed >MANUFACTURER< logo displayed 10secs
then >PERSONALBMP< displayed for 5 seconds
then >PERSONALMP3< plays once for 5 seconds
then >FINDMISSEDMESSAGES< check network
then >FINDMISSEDCALLS< check network
then >DISPLAYMISSEDALL< list by date/time
I suppose I could go on, but I am really saying that most people turn away from the mobile phone because they are either far too simple or far too complicated. Yet logic systems are not new. Our real limitations come with limited memory on PDA-type systems - or large memories on inflexible systems - or APP systems where most people are wanting an application but do not have the ability to write one, or don't know where they can go to enquire about it. Wishlists tend to end up on forums, with nowhere a manufacturer to be truly seen. I know that many people want to ask those same manufacturers about product implementations they would love to see, but can't find it on the HomePages.
I have spouted enough for now. I hope a few people have found this worth a read!!!
