What phone to buy Samsung Glaxy Mini(Pop), Fit or Ace?

This is a mail i wrote to my friend who asked me which one to buy of the three mentioned in the subject. Just posting it here as per his suggestion:

Glaxy ace (S5830) is more in price than than Pop (S5570 aka Mini) and Fit (S5670) so it will have more features and
better look and feel. Nevertheless other phones also has similar features. If u have a stringent budget, I would
suggest u personally see a demo and buy it. In case you are going to buy other than Ace. Some of my friends suggested Wave II check that also.

One of the key thing is look and feel. I liked Ace beacuse it was looking like i-phone to be honest. Check these
links for look and feel:

Another thing is touch sensitivity ( for this i recommend u c a demo), anyway u will notice the look and feel when u see a demo. Ace sensitivity is good.
- For your knowlege there are 2 types of touch screen: Resistive (depends on pressure) and Capacitive (depends on the conductive properties of touching material)
- I-phone and most touch senstive (Glaxy) uses capacitive. In low end smart phones Corby series uses capcitive touch screen.
- Nokia (many models I have seen) and low priced phones uses resistive that's not so sensitive.
- Normally resistive comes with Stylus and suited for finger touch.

Screen size is also very important for smart when (to read and edit document)
Screen size is comaprtive to price Ace has 3.5", Mini has 3.15" and Fit 3.31". Ace screen size is same as i-phone screen size for u to imagine the screen size.
The resolution is also better in Ace (which determines the clarity of display): Ace: 320x480 pixels and Fit: 240x320.

OS also plays a role in tocuch screen and speed:
- All 3 phones has android 2.2 Froyo.

Processer speed (Now a days became important for mobile also, as it does multitasking):
- Pop(Mini): 600Mhz
- Fit: 600Mhz
- Ace: 800Mhz (here ace is more powerful)
Even the flagship model Galaxy S has 1GHz processor only.

Camera (another key feature in a smart phone):
Pop: 3MP (No Flash)
Fit: 5MP (No Flash) - I see no flash as big drawback for 5MP camera.
Ace: 5MP (with Flash)

Batterry: Both Ace and Fit has the same power battery (1350 mAh) where as Mini(Pop) has 1200mAh, which is expected. I feel if Ace is powered with 1500mAh it will much better for battery backup, than it will increase the price. This is the battery used in Galaxy S which cost nealy 28K.
As one of the drawbacks i see we need to charge these smart phones daily comapred to normal phone which will come for 3 days. This is because of the display and the data featues it uses synch up with mail maps etc in background. There are ways to save power which u can use, reduce the display brightness and remove autosync up for mails. Other than these i dont see any drawback.

Audio, Office, Chat, Social and Mail applications are similar in all these 3 phones.

Price (most important thing): this is as on 1-Mar-2011
Model: Price (with VAT)
Pop: 8,846 (9,200)
Fit: 10, 144 (10,550)
Ace: 14,615(15,200) - I got it for 15,100/- (The actual price has decreased few 100's in weeks time. When i was

checking with tax it was 15,600/-).

If you are a techie guy then better go for Android phone, tight integration with Google service is Amazing!! you need to experience to feel it. I will compare with optimus later and provide my comments. I have not recommended because I am liitle biased towards Ace and I feel it more depends on what u need. So only I have listed the Key difference and advatages. I will check with my collgue also for some inputs, he only suggested me Ace so his inputs are worth it.

Reference:
1. Check "GSM arena" for specifications and user comments, click on the image in specs to see full sized image.
2. "Tech tree" review also help, in choosing in a price range check that, i will send u the link later.
3. I use univercell website to check the price, prices displayed are without Tax, Univercell also gives EMI option if ur buying online.

How to create alias for Windows command prompt

If you use windows command prompt too often then this tip will be very handy for you. Alias are useful way to access commonly used commands using a short version of it. In Unix/Linux, we have a command alias to do this. However in windows it is not straight forward. This post explains how to accomplish that in windows command to prompt.

Its a two step process (initially):

  1. Create a Windows cmd prompt shortcut in Desktop: This can be easily done by Holding the Ctl Key and drag cmd window shortcut in Programs-> Accessories to Desktop. This will create a Shortcut.
  2. Now modify the shortcut to execute a batch file at the start: This can be done by adding /q/k BATCHFILENAME after cmd.exe in Properties of Shortcut. I hope you are ware how get the properties, Right-click the Shotcut and Choose "Properties" in the context Menu. After the change it will look something like this (In my case batch file is stored at C:\Sara\ and filename is alias.bat).


One this is done, you are All Set. you can now add the commands to executed in the batch file. Sample file shown below, its self explanatory. Few things to understand are we use doskey command to create alias, and $* is in similar spirit to Unix/GNU Linux $* - it means all the arguments. Lines starting with REM are comments.

alias.bat:
REM ---------------------------------
REM Create alias for cleartool as ct
doskey ct=cleatool $*

REM Create alias for explorer as e
doskey e=explorer $*

REM Create alias for notpad++ as np
doskey np="C:\Program Files (x86)\Notepad++\notepad++" $*

REM Change intial dir to C:\Sara\scripts
cd /d C:\Sara\scripts
REM ---------------------------------

Now the same bactch file can be used to accomplish other task at start-up of command winddow: last example demonstrates that use.

How to kill several unwanted windows (or task) at once

While you work in Windows machine, sometimes too many instances of the same task gets started by mistake or triggered by virus etc and TOO many windows will be opened. Now how to kill all of them without the pain of clicking "Close" button several times. Easy way is to use a command: taskkill. To get started, use tasklist command - to see the list of task running currently. This command output is similar to TaskManager window (or in similar spirit to Unix/GNU Linux ps command). This command will list all the task as below (output from my machine). Just for Demo I have created several instances of gvim to run (that can be seen in below output). Now to kill all of them at once, use:
taskkill /IM IMAGENAME.
In this example it is: taskkill /IM gvim.exe. This will kill all instances of gim.exe (as shown below).

Demo on MS-DOS prompt:

C:\>tasklist
