Hi, RAM (random-access memory) have different speeds or cloc frequencies. Even in different SDRAM modules, there are different operating speeds. But high-emd RAM has a drawback: it's true that it will work better, but the faster a component becomes, more heat is required. On mobile devices, RAM has somewhat of a slower clock frequency - around 2700 (around 333 MHz) versus 4200 (533 MHz). Also, even though a document is opened on word processor, the actual file contents could be located somewhere else in RAM - I will not go into memory allocations, stacks versus heap, etc., but remember that a new instance of a program or data would be allocated on the first available memory address, which could mean that the data could be separated from one another, thus some performance problems (not a lot though).
Another thought: Windows CE 5.0 has a crucial limit: 32 MB of virtual memory. In other words, even though if we want to work with huge data and blocks of text, the memory manager has to worry about two things: how to avoid low memory problem with torrents of large data that's coming in, and how to allocate the best memory addresses so that the data are not broken - so that it would be contiguous? If there is low memory, there won't be any more room to continue working with large data - thus the risk of data loss and slowness increases. On the other hand, less contiguous data means that memory manager needs to find a "connection" between current part of the file to the next, thus the probability of performance degration increases as the data size increases i.e. it would be more fragmented across RAM. I will not go into how this is done (both because of my current education level and complexity in explaining it). In connection with my statement, the freezing with memory shortage does not occur with the other guy anymore - just freezing in executing function calls is seen. Besides, just like data size, some functions called to the operating system, such as moving files gives CPU some stress (this is called CPU usage). Anyway, just my thoughts. Hope this helps.

I am curious about something Joseph brings up, that of responsive speed. When, for example, you go to delete a block of text, there is a brief but noticeable pause before the function is performed. Is this owed to memory constraints, or is this simply a system delay? Or was my unit just special? I'm finally getting around to owning my own unit in a few weeks and can hardly wait.

Hi, That coparison is a bit out of date, as it compares the mPower, not the Apex. There is an updated comparison done by HumanWare, myself and Alex Hall on this list. I too, am interested in BSP line. However, I chose Apex mostly because of stability under the hood, reading experience, potential for system modifications i.e. more user tweaks and so forth. Besides, there is no more memory worries - at least no more messages like that on the mPower, but it is a bit faster than BSP (not by a lot though). Have you checked out Blind Cool Tech website? There are quite a few podcasts dealing with Voice Sense (if I remember right). Hope you'll find useful info on this list.

I wonder if the topic has been covered so many times that people aren't as forthcoming with their suggestions. I'm very familiar with the mPower, only somewhat familiar with the Apex, and I chose the Sense line of products because: 1. Closer similarity to the Windows environment 2. Logical command and menu structure 3. Mobile disk feature to avoid use of ActiveSync 4. Strong performing media player I specifically chose the BSP because of the much quieter keyboard than the Apex. It's not that I want to send you to the archives because I feel no one is interested in providing you a thorough response. It's just that I feel the topic has been thoughtfully covered before, and it would be easier for you to read those posts and then come back with specific questions so that you get all the information you need. Remember GW has a comparison chart you can access right off the product page. I'll post the link below for your convenience, but if you can get your hands on a Voice Sense, I think you'll find that is truly the best way to make an educated decision.

Hi all. I'd still love to hear from anyone who is prepared to share their thoughts of the Voice Sense especially if they have experience of using the humanware notetakers. Also, can anyone point me to any detailed reviews of the voice sense please? I'd really be interested in hearing how good it is in dealing with the internet, email and instant messaging. Also does it support html email? Many thanks again and sorry for all the questions.
